Bolts are threaded rods or pins that fasten objects together. They usually have a head at one end and a thread at the other. Bolts are secured by threaded nuts, and are available in both metric and non-metric designations. Search by Specification | Learn More about Bolts

...the dimensions of screws. The United States has its own system of non-metric screws called the unified threat standard, but in much of the world the metric screw has displaced many older systems. Common metric screw measurements include an M3 thread that has... Search by Specification | Learn More about Screws

...a tubular shape and no taper. Tapered devices have a conical form. Pin and plug gauges with ball-shaped ends are used to gauge spherical cavities and tapered holes. Hex or nut gauges have hexagonal or square cross- sections for gauging countersunk holes... Search by Specification | Learn More about Plug and Pin Gages

Nut runners are controlled nut drivers, often with torque transducers in the head. They are used in precision fastening and assembly applications, and can be interfaced with SPC software for quality control. Search by Specification | Learn More about Nut Runners

Captive screws are fasteners which remain attached to a panel or parent material, even after they are disengaged from the mating panel or part. They meld with the parent via cold forming, and then fuse with the panel or part into a single entity. Search by Specification | Learn More about Captive Screws
