1033093 SCREW CAP HEX SKT HD M4X25 LG SS A4 — BOLTON SKU 59030.
About the 1033093 Hex Socket Cap Screw, M4x25 A4
Article 1033093 is a hexagon socket head cap screw in the M4 x 25 mm size, listed against the DIN 912 standard and the Bossard BN 612 stainless range, with a coarse M4 thread of 0.7 mm pitch and a 3 mm hexagon key drive. DIN 912 is functionally superseded by ISO 4762, and the two share head diameter, head height and socket dimensions, so parts to either callout are interchangeable in most applications. A4 stainless steel is a molybdenum-bearing austenitic grade covered by ISO 3506, chosen where corrosion resistance in marine, humid or chemically exposed environments matters more than the higher tensile strength of alloy-steel property classes. The cylindrical head is designed to seat in a counterbore, and the internal drive allows tightening where there is no clearance for an open-ended or socket wrench around the head.
