RS PRO Pozi Pan Steel Machine Screws DIN 7985, M4x50.0mm

From the trusted RS PRO brand, these pan headed machine screws are ideal for use in electronic machinery. The high-quality machine screws are fully threaded and can be used in pre-tapped holes or used with conforming nuts and washers in through holes. The screws are bright zinc plated and offer a degree of environmental resistance, allowing them to be used in most indoor circumstances.

With a pozidriv recess, these pan head machine screws have been designed to guarantee ease of assembly.

• Plated zinc coating works as an effective barrier against the effects of wear, and helps prevent corrosion and abrasion

Sometimes referred to as machine bolts, machine screws typically fully threaded screws that feature smaller than average thread sizes. Wherever precision and security is required in fixings and fasteners, these machine screws are ideal, and so are often used in machinery fastening applications.

A Pozidriv screw is an improvement on the crosshead screw, or Phillips screw. Like the crosshead, the Pozidriv screw naturally centers the torque when a Pozidrive screwdriver is applied, meaning there is less resistance and more control when screwing and unscrewing. To lessen the chance of the driver slipping from the screw head, known as cam out, the Pozidriv screw is preferable even to the Phillips screw.

Pan head screws are different to countersunk screws in that they sit above the surface of the material. They can result in a more secure and accessible screw head, providing a smooth material surface isn’t a priority.
