This custom stainless steel knurled thumb screw, also named knurled adjustment stop pin and hand twist positioning pin, is fully manufactured by CNC Swiss automatic lathe in single clamping process.

Constructed from solid 304 stainless steel bar, the component features diamond knurling on the head for friction-enhanced manual tightening, straight slot on end face for auxiliary tool adjustment, standard external thread and precise cylindrical locating shaft.

Finished with natural matte stainless treatment without plating or anodizing, it maintains excellent rust resistance. As a professional OEM manufacturer, we deliver flexible custom service for all specifications of cnc machined locating pin and 304 steel fixture limit pin according to your technical requirements.
