Heavy Hex Bolts
Heavy Hex Bolts are designed for use in a variety of high temperature, high strength industrial applications, such as with steel fabrication and general construction. They feature a thicker head than standard or regular hex bolts, and offer a greater bearing surface that distributes the clamping load over a wider area. Heavy hex bolts can be made with a few different materials including low and medium carbon steel, alloy, and stainless steel.
Carriage bolts most commonly have a smooth, domed head with a square section underneath that pulls into the material to prevent spinning during installation. This feature allows for the bolt to be self-locking when installed through a square hole in a metal strap, or a round hole in most woods. It can be installed with a spanner or wrench.
T Head Bolts
T-Head bolts are mainly used with a nut to joint an object with a T shaped slot so that the head of the bolt sits flush or below the material surrounding it. T-head bolts can come in any requested coating or plating such as zinc, black oxide, silver and many others.
Hex Flange Machine Bolts
Flange machine bolts, also known as hex flange machine screws, incorporate a bearing face, or flange, that extends beyond the diameter of the head. This flange distributes the clamp load over a larger area. Some flange machine bolts feature locking serrations on the face of the flange that are designed to “lock,” or bite, into the material being fastened to provide resistance to loosening.
Bent bolts can be further broken down into the following categories based on the way they are bent and their intended application:
- Eye bolts. The head of these bolts forms a full circle-like the eye of a needle-allowing for the attachment of cables, ropes or other fasteners.
- Hook bolts. The unthreaded end of this bolt forms a hook shape that may range from a simple L-shape to more complex custom bends.
- J-bolts. These J-shaped bolts typically act as a hook, facilitating easy attachment and detachment from other components or structures, often in combination with eye-bolts.
- U-Bolts. This bolt is bent into the shape of a U with both ends threaded, enabling users to secure pipes or tubes to other components or structures.
- Anodizing – Aluminum, hard oxide surface, excellent corrosion resistance
