Carbon Steel Truss Hex Head Machine Screws Zinc Plated Coarse Thread For Industrial Equipment Assembly Bulk Wholesale

Machine screws are different from wood screws or self tapping screws. They do not cut their own thread. Instead, they need a pre tapped hole or a nut to hold tight. This makes them perfect for metal to metal fastening where you need a strong, reliable joint that can be taken apart later.

You get consistent clamping force every time. The thread runs the full length of the screw from under the head to the tip. This full thread design lets you use the screw with different material thicknesses. You can also take them apart without damaging the threads.
