Socket Set Screws, 4x4mm (4) (DUB2170)

Socket set screws, sized 4 mm in diameter by 4 mm long, are supplied as a four-pack. These compact fasteners are designed to secure components by threading into a hole and pressing against a mating part, delivering a flush, lockable hold without any protruding head.

With a socket drive, these screws tighten with an Allen wrench, enabling precise installation in tight spaces and on small assemblies. The four-pack format provides handy spares for projects or routine maintenance, making them a practical choice for compact, unobtrusive fastening needs.
