About the Torx Countersunk Head Screw M3x8, Stainless Steel
This Torx Countersunk Head Screw M3x8 Stainless Steel A2 is an M3 x 8 mm machine screw to ISO 14581, the standard for countersunk flat head screws with a hexalobular internal drive (commonly called Torx). The countersunk head sits fully flush in a matching countersink, leaving no protrusion above the surface — the head form to specify wherever a raised screw head would obstruct sliding parts, seals or adjacent components. The hexalobular recess in the M3 size is driven with a T10 bit per the standard, transmitting torque with less cam-out and lower drive-bit wear than cross-recess heads, which matters in driver-controlled production assembly. A2 stainless steel (304 type) gives general-purpose corrosion resistance. BOLTON supplies this screw against request for quotation; state quantities and any documentation needs in your RFQ.
