Machine Screws - Pozidrive Pan - BA

A machine screw is a type of screw that is commonly used in industrial and manufacturing applications to secure components within engines, electronic products and general machinery.

Pozidriv pan head machine screws have a slightly raised domed head, whereas with the slotted version the head is flat on the top – resembling an upturned frying pan.

Pozidriv refers to the recess in the head. This type of machine screw is installed with a pozidrive screwdriver or driver bit.

Pozidriv pan head machine screws are available in either a zinc plated or stainless-steel finish.
