Unbrako

Also known as an allen screw or allen bolt, or simply a cap screw. Socket head cap screws are a modern machine threaded fastener, an alternative to the standard hexagon headed bolt. The geometry of the hex drive mechanism means that these internal contact surfaces are protected from external damage. A hex or allen key is therefore required to fit these fasteners. Conforming to ASME B18.3 and material to ASTM A574, UNBRAKO® socket head caps are manufactured to be stronger than other size for size high tensile versions. Please note that due to the nature of the surface finish on Unbrako products, some surface corrosion may be evident. This does not affect the performance of the product. Minimum tensile strength of UNBRAKO® socket head caps is minimum 180,000psi which is similar to metric property class 12.9.

Socket Head Button Screws in a Black Oxide Finish. A popular socket head screw, typically used where a lower profile domed finish is required. UNBRAKO® branded and manufactured to be stronger than other size for size high tensile versions. Includes a precision hex socket for maximum key engagement. Recommended for moderate applications such as machine guards, hinges and covers. Please note that due to the nature of the surface finish on Unbrako products, some surface corrosion may be evident. This does not affect the performance of the product. Property class of 12.9, similar to ISO 7380.

A countersunk headed screw conforming with ISO 10642 or DIN 7991, requiring a hex key (otherwise known as an Allen key) to fit. The countersunk head is typically used in conjunction with a countersunk hole providing a flush, snag free fit. The head diameter is slightly larger than that of the equivalent DIN 965 Phillips or Pozi driven screw. UNBRAKO® branded and manufactured to be stronger than the other size for size high tensile versions. Includes a precision hex socket for maximum key engagement. Please note that due to the nature of the surface finish on Unbrako products, some surface corrosion may be evident. This does not affect the performance of the product. Property class of 12.9.

High quality and high strength low profile socket head cap screws. Unbrako branded, with a black oxide finish. Also know as low head Allen screws or bolts, or simply a low head cap screw. Used where there is limited clearance. Includes a precision hex socket for maximum key engagement. Please note that due to the nature of the surface finish on Unbrako products, some surface corrosion may be evident. This does not affect the performance of the product. Conforms to ISO 262, DIN 7984, 6912, ANSI B1.13M, with a property class of 10.9.

Unbrako Durlok® self locking, anti vibration hex head flange bolts. These are serrated flanged hex head bolts, which can be paired with the Unbrako Durlok® self locking serrated flanged nut. They both have a high tensile strength of 12.9 and a black oxide/self coloured finish. These heavy duty fasteners are suitable for situations where vibration and jarring occurs and where the joint is subject to high loads. They can be reused, as they are unlikely to be damaged by the adjoining surfaces. Durlok® Bolts are manufactured from alloy steel and are through hardened to give the same hardness from the tooth surface to the core. Durlok® Fasteners can be used at high temperatures up to 300°C.

High Tensile Socket Head Flange Button Screws in a Black Oxide Finish. A popular and attractive socket screw with an integrated flange offering a wider head for bolting softer materials, and used where a lower profile finish is required. UNBRAKO® branded and manufactured to be stronger than the other size for size high tensile versions. Includes a precision hex socket for maximum key engagement. Recommended for moderate applications such as machine guards, hinges and covers. Please note that due to the nature of the surface finish on Unbrako products, some surface corrosion may be evident. This does not affect the performance of the product. Property class of 12.9, similar to ISO 7380 part 2.

Unbrako branded knurled cup point grub screws are designed for use with softer materials or for inserting into an existing threaded aperture. The cup point provides more torque and gripping force than other types, and the knurling helps to reduce loosening from vibration. The knurls are angled ridges on the edge of the cup that when tightened have a ratchet-locking action, as they cut into the mating surface. Knurled cup point grub screws are not recommended for reuse once fitted, as the cutting edges of the knurls are deflected when tightened and their effectiveness for future reuse reduced. Please note that due to the nature of the surface finish on Unbrako products, some surface corrosion may be evident. This does not affect the performance of the product.
