Hex Socket Cap Head Screw M3x35 SS A2 Partial Thread — BOLTON SKU 56306.
About the Hex Socket Cap Head Screw M3x35
This screw hex socket cap head item is an M3 x 35 mm cap screw in A2 stainless steel supplied with a partial thread, meaning a length of plain unthreaded shank sits between the underside of the head and the start of the thread. The thread itself is M3 with the 0.5 mm coarse pitch. A partially threaded screw behaves differently from a fully threaded one: the smooth shank can locate in a reamed or close-clearance hole and carry transverse load on solid metal instead of on thread crests, and the thread engages only in the far component. The head is the cylindrical cap form with an internal hexagon drive. A2 is the chromium-nickel austenitic stainless grade for general service. The governing dimensional standard and the exact shank-to-thread split are not stated on the part record, so confirm both when enquiring.

Typical applications
Selected for M3 joints where the unthreaded shank is wanted in the clearance hole — light linkages, pivots, hinge details and located brackets that see side load as well as clamp load. The 35 mm length allows the shank to pass through a reasonable stack before the thread picks up in the tapped component. Where the shank is not needed and the grip must be adjustable, the fully threaded M3 equivalent is usually the better choice.
