For aerospace applications, the gap is sometimes designed to be 0.03125 inches, but this requires smaller brackets and flange tolerances, which usually results in higher costs. Without the gap, no flange can wedge better together no matter how much torque is applied. When the gap is too large, the bracket will be subjected to greater stress, which reduces performance and can lead to installation difficulties (the real problem is often misdiagnosed as the bolt is not long enough to tighten the nut).
Flanges must also be reasonably designed and manufactured in order to fit well with V-shaped clamps/joints. Poorly designed flanges can cause many problems that are often initially attributed to V-shaped clamps/joints. There should always be a difference between these two vertices (widths), and depending on the specific design specifications, the total flange vertices should be larger than the clamp vertices. The calculation of the clamp and flange vertices is based on the theoretical intersection of the straight lines taken from the clamp and flange contour sides and vertices.

Black oxidation: A dark black protective coating obtained through a chemical process.
Slotted tongue blade: A tongue blade with a side. The side design provides additional rigidity and is therefore suitable for situations where the flat tongue blade is not enough to prevent the hose (especially soft hose or silicone hose) from being squeezed. It is fixed by welding.

Downsizing: refers to the maximum downsizing of the nominal diameter of a given clamp, or minus that nominal diameter. After subtracting this value, you get the minimum diameter of the clamp installed on the hose and still able to form a good seal. The downsizing is only applicable to belt clamps, not to V-type clamps / joints.
Electrolytic polishing: a process that uses electrical energy to remove surface scratches, discoloration, oxides, etc., to form a clean, bright, bright surface.
Floating bridge: A tongue-shaped component with sides that is secured to the fixture by loose clamping. This allows the floating bridge to slide independently at both ends when tightened through a T-bolt, shaft neck and nut hoop, thus achieving a “floating” position. The component is also used to prevent the extrusion of hoses, especially hoses or silicone hoses, during the installation of the fixture.
Biting: refers to the phenomenon of friction between the surfaces of the same metal. This can be avoided by properly lubricating the surface of the bolt or nut (or both). Biting is more common between the same metal, especially between the same or similar stainless steel, so it should be avoided as much as possible.
Housing: The fasteners on the snail clip are connected to the clamp to fix the snail to the hole in the clamp and provide an additional bearing surface for the snail. The housing of the Clampco snail clip is made of 300 series stainless steel.
ID: The inner diameter of the hose or flange. This is not the correct diameter for the selected clamp size.
Knob: A plastic component with a metal threaded insert to replace a metal nut for hand tightening and easy removal.

Nominal Diameter: refers to the “ideal” or “normal” diameter in the design of the fixture after the correct selection of size and correct installation according to the expected outer diameter. Due to certain limitations of the fixture, there is an orderable nominal diameter limit (or minimum nominal diameter) for each T-type bolt belt fixture series.
OD: Outer diameter; the key measurement value of the hose or flange used to correctly determine the diameter of the fixture.
Over-Center Handle: A hinged fastener assembly for use with winding T-bolts that can be opened and closed without the need for tools after initial installation. Available in light, medium and heavy stainless steel models.
Quick release latch: A hinged stainless steel latch assembly for quick removal or replacement of a winding T-bolt. The latch must be used in conjunction with a winding T-bolt to remove the fixture without completely unscrewing the nut at the end of the T-bolt. The quick release latch is fixed by the ring end of the fixture and is rotatable.
Saddle quick release buckle: A fixed stainless steel component for quick removal or replacement of T-bolts. The buckle does not need to be fitted with a winding T-bolt, so the fixture can be removed without screwing the nut completely off the end of the T-bolt. Saddle quick release buckle is welded to the fixture belt.
Self-locking nut: A nut that can be locked in place when tightening (reaching torque) the bolt. Within a certain stroke range on the bolt, the self-locking nut will not loosen due to vibration. If there is no vibration in the application, non-self-locking nuts can be used to save costs.
Silver plating: A layer of silver is deposited on the metal surface by electrolysis to obtain a glossy surface. It is used to form a fine protective layer and/or prevent bites. It is widely used in nuts, especially stainless steel locking nuts, to prevent bites. Silver liquefies and flows at high temperatures, thus playing an excellent lubricating role between the same stainless steel materials.
Stainless steel clamps: Stainless steel clamps can be T-type bolt clamps or V-type clamps. The term “stainless steel clamp” refers only to the material of the clamp. For example, Clampco typically uses 301, 302 and 304 stainless steel materials in its stainless steel clamp products. Clampco also produces 316 stainless steel clamps for use in ships and other highly corrosive environments.
T-bolt clamps: Because of their T-shaped fasteners, T-bolt clamps are sometimes also referred to as T-bolt clamps. For a complete definition, see T-bolt belt clamps.
T-bolt: A cold-rolled bolt with a “T” shaped head. A variety of lengths, materials and thread specifications are available. If necessary, the width of the T-head can be increased by adding a coating. T-bolts can be made of stainless steel, coated alloy steel or other special materials.
T-type bolt belt clamping: a stainless steel belt ring clamping, the basic locking method is T-type bolts, shaft necks and nuts. There are other locking methods available. Bandwidth, thickness, material and type, size and material of components can be flexibly adjusted to achieve a variety of combinations. Common configurations and sizes are in stock.
T-type bolt clamp: The terms T-type bolt clamp and T-type bolt belt clamp can be used interchangeably. See the definition of T-type bolt belt clamp.
T-shaped handle: A metal T-shaped handle used to replace the nut for hand tightening and easy removal. The material can be stainless steel or plated steel.
Tongue Sheet: An additional sheet of steel, rolled into the same size as the diameter of the clamp, welded to cover the gap under the latch. Used to form a “perfect circle” seal, and/or to prevent the clamp from squeezing the hose when tightening a plastic or rubber hose. The tongue sheet can be flat or have sides.
Torque: The force required to tighten the clamping nut is multiplied by the distance (units can be inch pounds or newton meters). No single torque value applies to all installation scenarios, but there is a maximum torque value for each clamping component combination that should never be exceeded. The appropriate torque value varies by application and must be determined by the customer.
Ear shaft: A type of “T” liner or bearing element through which a T-type bolt passes. One end provides a support surface for the nut, and the other end pushes the earshaft ring end of the fixture. For maximum strength and corrosion resistance, the earshaft should be made of stainless steel body and stainless steel cover. Under the same thickness, the strength of two-piece earshaft is superior to all-in-one earshaft. The earshaft is widely used in a variety of T-type bolt locks, including standard T-type bolt locks.

V-Clamps: Stainless steel material with V-clamps for internal welding. For connecting pipe, pipe fittings or container components, these components must be designed to match the corresponding V-clamps. V-clamps are synonymous with V-clamp joints.
V-type clamps: Stainless steel clamps with V-shaped clamps for internal welding. For connecting pipe, pipe fittings or container components, these components must be designed to match the corresponding V-shaped clamps. V-type clamps are synonymous with V-type clamps.
V-shaped clamp: A V-shaped stainless steel component welded to the inside of a V-shaped clamp/fitting. V-shaped clamps are used to wedge and secure flanges at the ends of pipes, tubes or container connections such as filter bodies and lids.
Snail: One of the main fastening components of the snail snail clamp. The snail is essentially a hexagonal head helical threaded shaft, engaged with the grooved clamp, when applying torque, the snail will bite the hole on the clamp, thereby tightening the clamp. The snail is located in the body of the snail snail clamp.
Coating: Additional sheet of metal formed around the T-type bolt head, typically in stainless steel, to provide additional bearing surface
