Tab Bolts

Tab Bolts Tap bolts are fully threaded hex bolts. Unlike tapping screws, tap bolts do not form their own mating internal threads. They are instead designed to be inserted through holes in assembled parts and tightened by torqueing a nut, or mated with an internally threaded (tapped) hole and tightened by torqueing the bolt's head just like their hex bolt counterparts. 
 
The tap bolt should be long enough to allow at least two full threads to extend beyond the nut face after tightening, which ensures full thread engagement with the nut. Having many threads within the grip (the area between the head and nut), as is the case with tap bolts, results in a "springier" bolt. It is also recommended that threads not be in the shear plane(s).
 
Nickel Systems maintains an inventory of tap bolts because many customers require fully threaded parts. Additionally, this allows us to cut parts to non-standard lengths on short notice or cover requirements for standard lengths which may be temporarily out of stock, and still provide an adequate thread length.

Most of the smaller diameter (1/4? through 3/4? and MM sizes) bolts we stock in Hastelloy® C (Alloys C276, C22, B2), Carpenter® 20 (Alloy 20) and Duplex 2205 are fully threaded. Inventory of larger diameter tap bolts varies with market demand.

Tap Bolts are most commonly used in industrial work, but are not designed for high-pressure or high-temperature applications. We manufacture these tap bolts up to 6 inch long in materials like stainless Steel, nickel alloys, copper alloys, brass alloy, steel etc. We also provide passivation, quality coating further processing as per client's requirement.
