Brass knurled nuts for applications where a fastener needs to be adjusted and secured to a finger-tight degree. Precise knurls clearly formed; optional face knurls help lock the parts in place.
Brass knurled nuts are fasteners with a knurled outer surface designed to be tightened and loosened by hand, without tools. The knurled grip provides enough friction for the operator to apply finger-tight torque reliably. Prime manufactures knurled nuts in a complete range of thread sizes, knurl patterns and finishes — with custom designs produced to drawing.
Our standard range begins at M2 and runs up to M20, with custom sizes available. Knurl options include diamond, round, straight and unidirectional patterns; both blind and through configurations are offered.

Knurled nuts are specified anywhere a tool-free, hand-tightened fastener is preferred — for frequent adjustment, quick assembly, or operator-facing controls.
Beyond catalogue range, Prime develops knurled nuts to customer specifications — custom knurl depth, head profiles, thread forms, lengths and brass compositions.
