Every part is produced to OEM specification with full traceability and first-article inspection. ## Specifications Part Number 70400-01625-103 Description Nut Component Type Pins, Bolts & Fasteners ## Manufacturing Pins, Bolts and Threaded Fasteners Pins, bolts and threaded fasteners in flight safety-critical applications are subject to inspection requirements well beyond commercial hardware. TEK Precision is a certified threaded fastener facility, operating a complete Johnson thread gaging system from #10 through 2.500 with Method "C" and safety-critical capability. Thread inspection draws on more than 300 thread plug gauges and more than 300 thread ring gauges from 4-40 through 7.000, each with a matched thread setting plug, supported by precision thread measuring wires and thread pitch micrometers covering 14 through 32 pitch. Turning is performed on CNC turning centres and on Hardinge DV-59 and HLV-H precision lathes for smaller work. Ground diameters are finished on Tschudin cylindrical grinders to 0.000002 inch resolution. Hardness is verified on Wilson hardness testers per ASTM E-10, E-18, E-92 and E-384, and ground surfaces are temper etch inspected for grind burn per SS8705 where the specification requires it. ![Representative photograph of a polished threaded aerospace rod-end fastener component produced by TEK Precision](/__l5e/assets-v1/d8e9553e-fc4e-419c-a1ba-643a3715dc57/photo-10.webp) Representative pins, bolts & fasteners manufactured by TEK Precision.
