Product Description
M4 A2 Stainless Steel Socket Flange Button Screws — ISO 7380-2
M4 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 2.5mm Allen key drive, these screws are suitable for panels, covers, brackets and general assembly. Choose from twelve lengths between 6mm and 60mm.

Measuring and Fitting
Measure screw length from the underside of the flange to the tip. Use with a matching M4 x 0.7mm nut or tapped hole, allowing sufficient thread engagement for the assembly.
Fully engage a correctly fitting 2.5mm Allen key before tightening. Tighten steadily and avoid excessive force to protect the socket and stainless steel threads.
