Manufacturing
We use several different methods of manufacturing for our aerospace fastener lines:
- - Head forging
- - CNC machining
- - Centerless Grinding
- - Thread Rolling
Cold and hot head forging methods are used to manufacture our wide variety of standard and oversize fasteners. These include the Hi-Lok™ and Hi-Tigue™ fasteners, straight shank pins, customer special orders and our new, light-weight Ultra-Lite™ fastener.

Production Processes
Cold and hot heading and secondary operations are used to finish the fastener blank.
Typical finishing methods include:
- Head turning and trimming.
- Endpoinnting.
- Drilling and broaching the hex recess in the thread end of the Hi-Lok™ and Hi-Tigue™ series Fasteners.
- Precision centerless grinding.
- Tapping
of the expander nut and Hi-Lok™ collars.
- Filet rolling, which is the controled cold working of the shank to the head filet radius.
- Hot and cold Thread rolling is done using the two-die reciprocating method, and
Reed thread rollers are used for larger diameters.
These finishing methods also include Hi-Kote™1 and Hi-Kote™2 and other plating methods.
