Knurled Screw

Knurled screws, or more precisely screws with a knurled head, are used to create quick-release joints in instrument and machine manufacturing. The design of knurled screws complies with GOST 14731-69 and/or GOST 10344-80. The distinctive feature of this fastener is the unusual shape of the head: it is round or square, with a diamond-pattern knurling on its side surface. This allows the screw to be screwed in and out easily by hand, without using tools.

Knurled screws are installed where a structure needs to be periodically disassembled and reassembled, such as instrument housings or server cabinet panels. The threaded shank is short, so the screw unscrews quickly. Between the shank and the knurled head there is a shoulder that ensures reliable clamping of the screw against the working surface.
