Description
ISO 4762 Socket Head Cap Screw M3x8 Steel — BOLTON SKU 56533.
About the ISO 4762 Socket Head Cap Screw M3x8
Supplied against this SKU is an ISO 4762 Socket Head Cap Screw in the M3 × 8 mm steel size — the shortest M3 length in this group. Dimensions follow the ISO 4762 cap-screw table for M3: 0.5 mm coarse pitch, 5.5 mm maximum head diameter, 3.0 mm head height and a 2.5 mm hexagon socket. An 8 mm length is intended for thin flanges, covers and shallow tapped holes where a longer screw would bottom out before clamping. The cylindrical cap head recesses neatly into a counterbore, and the internal drive allows tightening in locations where surrounding components block spanner access. The item is recorded as plain steel; the property class and any surface finish are confirmed from manufacturer or mill documentation at the quotation stage, together with quantity and packaging requirements for the order.
