Hex Head, Hex Socket with and without holes, Flange, Shoulder, Square, and T-Bolts
1/8” to 1.00” diameters and lengths to 3”
Washer on the underside of a hex head. Helps in distribution of force from the bearing load. Also referred to as frame bolts.
Frame applications such as truck and bed frames
Bolts are fully or partially threaded, with six-sided heads.
Broad range of uses, including construction and repair of bridges, docks, highway elements and buildings.
Square heads paired with a semi-cone point and a fully threaded shaft.
Fastens wood to wood, wood to metal and metal to metal. Also found in general hardware use.
Also known as shoulder screws. A long unthreaded, cylindrical shank helps rotation of attached moving parts.
Pulleys, moving engine parts and mechanical assemblies, gears and rolling wheels.
Consists of a square head, followed by a smooth shank and a machine screw thread. Can also be fully threaded. Design of the head facilitates easier wrench grip when tightening.
Wide range of industrial, agricultural and construction applications.
(“Hammer-head bolts”) have a T-shapedhead, and are manufactured to fit a slot in a drill swivel head. The swivel head can then be positioned at any angle to drill a borehole.
T-bolts can be flexibly placed within anchor channels. They are used to fasten guide rails, to clamp fixtures/tooling to work areas, in T-Trackclamping systems, throughout the automotive aftermarket and in leveling systems. They can be manufactured cost-effectively in runs of all sizes.
The head thickness and flange diameter of this bolt is equivalent to the head dimensions of socket head cap screws – and the two terms are often used interchangeably.
The design of the 12-pointbolt allows the screw to be tightened with a 12-pointsocket wrench, making higher torques possible and eliminating the rounding of the hex socket that happens with standard hex sockets.
12-point bolts have an aesthetic advantage over cap hex or socket head cap screws and are preferable in recessed applications
