Q. What is the difference between machine screws and bolts?

A. Machine screws and bolts are similar but differ in their intended use. Machine screws are designed to be used with nuts or tapped holes, while bolts have a larger diameter and are used with threaded holes or in conjunction with nuts.

Q. Can these tamper-resistant screws be used in conjunction with washers?

A. Yes, these screws can be used with washers to distribute the load and provide a larger bearing surface, especially when fastening softer materials or when extra reinforcement is needed.

Q. What is the difference between machine screws and wood screws?

A. Machine screws are primarily used to fasten metal parts together, while wood screws are designed specifically for use with wood. Wood screws have coarser threads and a tapered point to penetrate wood fibres effectively, whereas machine screws have finer threads and a blunt end.

Q. What are the main components of a machine screw?

A. A machine screw consists of three primary parts: the head, the shaft and the thread. The head may be flat, oval, round or another shape and provides a surface for tightening the screw. The shaft is the straight portion of the screw between the head and the thread. The thread is the helical ridge that wraps around the shaft, allowing the screw to grip the material it's being fastened into.
