What is the difference between machine bolts and machine screws?

Machine bolts are often confused with machine screws. Generally, machine screws are smaller in size compared to machine bolts, but are fully threaded. Machine bolts have a flat tip, not a pointed / tapered tip as seen in screws. Screws are typically used in pre-tapped holes or driven into materials for creating their own threads when tightened. In contrast, machine bolts are often paired with nuts at the end of the bolt for torquing during installation. Nuts are not generally mated with screws.

What are the thread fits or classes in these machine bolts?

Thread fit grades or classes of a fastener indicate the degree of looseness or tightness of mating threads. Generally, the higher the class number, the tighter the fit of the attached components (like nuts). Lower thread fit grades / classes are suitable for applications requiring quick assembly & disassembly. Higher thread classes are ideal for close tolerances, safety & strength.

What do the strength grades / classes mean in machine bolts?

The grade or class of a machine bolt denotes its strength & compatibility with the respective nut. Generally, the higher the grade, the higher the strength of the fastener. SAE grades are used for Imperial-sized bolts. Bolts having the same SAE strength grade as a nut should be used together. ISO classes are used for Metric-sized bolts. Bolts having the same first digit as a nut are meant to be used together. ASTM grades are based on factors like strength, high pressures & high temperatures.

Machine Bolts

Machine bolts are used to fasten two pieces of wood or metals in manufacturing & construction applications. Raptor Supplies offers machine bolts from brands like Proto, Texas Pneumatic Tools, Thomas & Betts, Fabory, Vulcan Hart and more. They can be paired up with a threaded nut to be inserted into pre-drilled holes and provide tightening torque for joining materials together.

Features

A machine bolt is mainly divided into 2 parts: the head and the threaded portion.
The head is available in multiple drive styles for driving the screw in / out from the surface and sticking out of the surface.
The threaded portion starts just below the head for mating with a nut after installation.
This nut & bolt assembly creates compression force that holds two loose objects together and can be disassembled easily when required.
Selected bolt heads are equipped with a square neck for preventing accidental spinning / opening due to vibration.
Most machine bolts are fully threaded (but some are partially threaded) for preventing loosening, rotation, breakage & bending caused by friction-induced overheating or sideway forces.
These bolts can be fitted with a washer for increasing the surface area and distributing the attachment force applied.
Fabory machine bolts are available in hex head, square head, step & elevator bolt variants.
Texas Pneumatic Tools machine bolts have hexagonal / square heads for easy installation. Selected models may also have a long stem for fastening parts in industrial machinery.
