Product Description
M8 A2 Stainless Steel Socket Flange Button Screws – ISO 7380-2
M8 socket flange button screws manufactured from A2 stainless steel, featuring a rounded button head with an integral flange. The wider bearing surface helps spread the clamping load across the mating surface, while the internal hexagon socket allows tightening with a 5mm Allen key.
Suitable for general assembly, machinery, panels and maintenance applications requiring corrosion-resistant fasteners. Available in lengths from 10mm to 60mm, with an M8 metric coarse thread.

Fitting Information
Use a 5mm Allen key or suitable hexagon driver, ensuring it is fully seated before tightening. Fit into a matching M8 x 1.25mm tapped hole or use with a compatible M8 nut. Choose a length that provides sufficient thread engagement without bottoming out in a blind hole.
Tighten stainless steel fasteners steadily and avoid excessive speed to help reduce the risk of thread galling. Where appropriate, use a suitable anti-seize compound and account for lubrication when determining the tightening torque.
