Hexalobular (6 Lobe) Socket Pan Head Screw M2x10, Stainless Steel A4, Fully Threaded — BOLTON SKU 67418.
About the Hexalobular 6 Lobe Socket Pan Head
This fastener is a small machine screw with a pan head and a hexalobular (six-lobe) socket drive, supplied in A4 austenitic stainless steel and threaded over its full length. The thread is M2 with the ISO metric coarse pitch of 0.4 mm, and the length under the head is 10 mm. A hexalobular recess transmits torque through six lobed flanks rather than through flats or a slot, which reduces driver cam-out and allows a compact head profile — useful at M2, where the available drive area is very small. The pan head presents a rounded bearing surface of comparatively large diameter, spreading load on thin or soft materials without needing a countersink. A4 is the higher-corrosion-resistance grade among the ISO 3506 austenitic stainless classes and is normally chosen where marine, humid or washdown exposure is expected. This variant is catalogued under manufacturer reference 3183828 screw hexalobular pan head, M2 x 10 mm, in A4 stainless steel.

Typical applications
M2 pan head screws are used for mounting light electronic assemblies, printed circuit boards, small brackets, covers, labels and enclosure hardware, where the fastener must clamp thin panels without pulling through. The hexalobular drive suits powered assembly and repeated maintenance access at this small size, and the A4 stainless grade allows use on externally exposed or humidity-cycled equipment.
