M10 Shoulder Bolts 18-8 Stainless Steel

M10 hex socket head shoulder bolts in 18-8 Stainless Steel to ISO 7379. A shoulder bolt — also called a shoulder screw or stripper bolt — has a precision-ground unthreaded shoulder between the head and a smaller thread. The shoulder is the working surface: it locates and pivots, letting a bushing, bearing, roller, linkage or stripper plate turn or slide on it while the thread below anchors into the tapped hole. Because the shoulder bottoms against the mounting face, clamp load never reaches the moving part, so the joint can be tightened fully without binding it. Standard in jigs and fixtures, stamping dies, conveyors, robotics and machine guarding. The thread is one standard size below the shoulder: 10mm shoulder, M8-1.25 thread. Length is the ground shoulder length measured under the head; the 13mm thread is additional. 10 shoulder lengths (12mm to 60mm). Sold in bulk multiples.
