Square Head Bolts from PTP

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.

T-Bolts
T-Bolts from PTP

(“Hammer-head bolts”) have a T-shaped head, 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-Track clamping systems, throughout the automotive aftermarket and in leveling systems. They can be manufactured cost-effectively in runs of all sizes.

Specialty 12-Point Bolts
12-Point Bolts from PTP

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-point bolt allows the screw to be tightened with a 12-point socket 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

PTP manufactures bolts and other precision fasteners for aircraft, rotocraft, and space vehicles.
