6-Lobe Hexalobular Cap Screws (Torx Head Bolts) In Stock
Hexalobular (6-Lobe) cap screws to ISO 14579, have a six lobe recess and are driven using a 6-Lobe wrench or insert bit, making them more efficient than slotted screws and hex drive screws. Also known as Torx head capscrews or allen bolts. These screws have a cylindrical head and six lobe socket drive and are most commonly supplied in 12.9 grade steel, making them a high strength fastener suitable for the most demanding applications. The hexalobular drive has more resistance to cam out and can be used with power drivers enabling faster use and higher torque to be achieved.
Available from stock in steel grade 8.8, 12.9, A2 stainless steel, A4 stainless steel. Other materials including brass, aluminium and titanium are available to order. Sizes range from M2 to M20, with larger diameters and lengths available to order.
We also also offer hexalobular socket cap head screws in UNC, UNF, BSW and BSF, with tamper resistant security drive also available upon request.
