Product Description
M2 A2 Stainless Steel Socket Cap Set Screws
Fully threaded M2 socket cap set screws manufactured from corrosion-resistant A2 stainless steel. These metric coarse screws have an M2 x 0.4mm thread and an internal hexagon socket for installation using a 1.5mm Allen key or hex driver.
The cylindrical socket cap head provides strong, positive tool engagement while allowing installation where access around the head is restricted. Suitable applications include precision engineering, electronics, machinery, equipment assembly, maintenance and general fastening.
In this listing, “set screw” means a fully threaded headed screw. These products should not be confused with headless socket grub screws.
