Socket Head Cap Screws

Socket head cap screws are threaded fasteners that have a cylindrical head and a recessed hexagon drive. Also known as Allen head screws, they are turned using a hexagonal key for Allen key engagement. Their torque specifications can be much higher than those of recessed / slotted fasteners. Socket head cap screws are ideal for fixing or clamping removable parts or sheets in machine assemblies. They are also widely used in applications with insufficient clearance to use a fastener with an external hexagon head. Raptor Supplies offers a wide range of flanged, flat and Metric socket head cap screws from brands like Micro Plastics, Morse Drum, Camcar, Foreverbolt, Grainger, Kerr Lakeside, Lisle and Snap-Loc. Grainger socket head cap screws feature a hex head for easy tightening and loosening using socket wrench drives. These flat head cap screws are less likely to snag clothing or linkages and are available in drive sizes ranging from 2 mm to 12 mm.
