Types of Custom Bolts Manufactured
Anchor Bolt
This Anchor bolt enables builders to embed items in concrete. We manufactured ½” to 4” / M12 to M100 dia. Bolts.
Bent Bolt
The bend of the bolt is used to keep materials in place without providing any room for radical movement. We manufacture Eye Bolts, Hook Bolts, J-Bolts, U-Bolts from ½” to 4” / M12 to M100 dia. In different grades.
Carriage Bolt
Carriage bolts are commonly used to attach wood to metal. The carriage bolt may be distinguished by a square formation located under its smooth, rounded bolt head. This shape helps prevent it from turning during tightening.
Countersunk Bolt
Countersunk Bolts are flat headed bolt fasteners with hex socket drive into the head. This provides a smoother exposed finish and allows moving parts to function within tight clearances.
Elevator Bolt
Elevator bolts are threaded fasteners with a thin body and round head. The head is undercut with a square shape to hold it in place during tightening, but it has a thinner head that can be made flush or near-flush with the attached surface.
Lag Bolt
These bolts include threads on only a portion of the bolt. This lack of threads is known as a lag. It facilitates a smooth surface attachment to wood, while the threaded end is more like a wood screw rather than a typical bolt thread designed to receive a nut.
T-Bolt
A bolt having with a head of square or rectangular shape intended to fit a T slot. T-Bolt clamps provide uniform sealing pressure for a positive, reliable seal. Designed for use in high vibration and large diameter applications.
Pin Hole Bolt
A pin bolt is normally a bolt that joins two separate, hinged objects together. Pins are used when it is necessary to connect, mount, fix and seal components.
Flange Bolt
Sometimes called frame bolts, flange bolts are common for load bearing applications. The heads of these bolts are undercut with an integrated flanged washer face located under the head to distribute stress from a load over a broader area.
Round Bolt
A Round bolt combines several distinguishing features from other bolts into a durable fastener often used in structural situations. Round bolts include a Round head, allowing flush mounting to hold the bolt in place during tightening.
