Zoro Select M3 Socket Set Screws

This Zoro Select pack contains 100 metric socket set screws with an M3 x 0.50 thread pitch and 5 mm overall length. Each screw features a headless cup point and a 1.5 mm socket drive. The alloy steel fasteners have a black oxide finish and are supplied as a small pack.

Check thread size and drive tool before ordering

Verify that the mating holes or shafts accept an M3 x 0.50 thread and 5 mm engagement length. Ensure a 1.5 mm hex key or driver is available for installation. The cup point design suits permanent or semi-permanent location on shafts, so confirm the application does not require a dog, flat or cone point instead.

Suits maintenance kits and small assembly runs

These screws suit technicians and hobbyists needing a ready supply of M3 cup-point set screws for fixtures, knobs or gear locking. Buyers requiring larger diameters, longer lengths or different point styles should look at other fastener options. The 100-piece quantity covers multiple small jobs without excess bulk.

Questions about this item

What does the pack of 100 socket set screws include and is a 1.5 mm hex key supplied?

The pack contains 100 M3 x 0.50 mm cup-point socket set screws, 5 mm long with a 1.5 mm drive. A hex key is not included and must be purchased separately.

How do I choose between the listed thread size and length for my application?

The only variant offered is M3 x 0.50 mm thread with a 5 mm overall length; select this pack when those exact dimensions match the tapped hole and required engagement depth.

What does the 1.5 mm drive size mean when I install these screws?

It means a 1.5 mm hex key fits the internal socket, allowing you to drive the headless cup-point screw flush or below the surface in a metric M3 threaded hole.
