Single-End Studs

Screw the threaded end of these studs into a tapped hole, and use the unthreaded end as a pivot point, hinge, shaft, or locator pin.

18-8 Stainless Steel—Made from 18-8 stainless steel, these studs are chemical resistant and may be mildly magnetic.

Steel—These studs are steel for strength and wear resistance. They’re best for dry environments since moisture will cause them to rust. All meet ISO 2342 (formerly DIN 427), an international standard for fastener dimensions.

Threaded Locating Pins


Round Head	Diamond Head

Screw the shank into a threaded hole for quick installation and removal. Mate these pins with holes in workpieces for precise alignment.

Diamond Head—Diamond-head pins make less contact with the inside of a hole than round-head pins to reduce sticking and jamming.
