Metric Partially Threaded Studs

Screw the threaded end of these metric studs into a tapped hole and use the unthreaded end as a pivot point, hinge, shaft, or locator pin. All can be installed and adjusted by hand or with a slotted screwdriver. 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.

Partially Threaded Studs with Cotter Pin

Also known as hood pins, these studs have a cotter pin lodged through a drilled hole in the unthreaded portion for light duty holding, such as securing access panels and locking other fasteners. Stud and cotter pin are 18-8 stainless steel, making them chemical resistant and mildly magnetic.
