UNF Countersunk Socket Screws – Imperial Fine Thread

Shop by Category

UNF

Our range of UNF countersunk socket screws features imperial Unified National Fine thread forms designed for precision fastening applications. With an internal hex drive and countersunk head, these screws provide a flush surface finish once installed.

UNF threads offer a finer pitch compared to UNC, making them suitable for applications requiring improved adjustment and clamping performance. Available in multiple diameters and lengths, our UNF countersunk socket screws are supplied in high tensile and stainless steel grades to meet engineering and automotive requirements.

Browse the selection below and use the filters to refine by thread size, length and material to find the correct UNF countersunk socket screw for your application.
