Product Description
M3 A2 Stainless Steel Socket Flange Button Screws — ISO 7380-2
M3 socket flange button screws manufactured from A2 stainless steel. The rounded button head incorporates a flange that provides a wider bearing surface beneath the head, helping spread the clamping load across the component.
Featuring a metric coarse thread and a 2mm Allen key drive, these screws are suitable for panels, covers, brackets and general assembly. Choose from nine lengths between 4mm and 25mm.

Measuring and Fitting
Measure screw length from the underside of the flange to the tip. Use with a matching M3 x 0.5mm nut or tapped hole, allowing sufficient thread engagement for the assembly.
Fully engage a correctly fitting 2mm Allen key before tightening. Tighten steadily and avoid excessive force to protect the socket and stainless steel threads.
