The Fastener Specialist - Asia Bolts & Nuts Manufacturer of bolts and nuts, fasteners for export

Glossary of terminology on topics related to nuts and bolts, threaded fasteners and tightening techniques.

A torque prevailing nut of all metal construction. The collar of the nut is elliptical in cross section and it is this that provides the flexible locking element. The nut is pre-lubricated to reduce the tightening torque. Cleveloc is a registered trade name of Forest Fasteners.

The effective diameter of a thread but allowing for errors in pitch and flank angles.

The compressive force which a fastener exerts on the joint.

A bolt whose diameter is less than the minor diameter of the thread. Frequently the shank of the bolt is 0.9 times the root diameter.

A threaded insert that is typically used for tapped hole repair or to improve the thread stripping strength of softer metals such as zinc and aluminium.

The inserts are assembled into a previously tapped hole using a special driving tool. A thread locking compound is frequently used to secure the insert if the assembly is subject to vibration.

U BOLT - A U shaped fastener threaded at both ends used primarily in suspension and related areas of vehicles.


The Class of Fit is a measure of the degree of fit between mating internal and external threads. Three main Classes of Fit are defined for metric screw threads :

FINE: This has a tolerance class of 5H for internal threads and 4h for external threads.

MEDIUM: This has a tolerance class of 6H for internal threads and 6g for external threads.

COARSE: This has a tolerance class of 7H for internal threads and 8g for external threads. For Unified threads, a similar designation as for metric threads is used.

The thread classes used are 1A, 2A and 3A for external threads and 1B, 2B and 3B for internal threads.

ULTRASONIC EXTENSOMETER - An instrument which can measure the change in length of a fastener ultrasonically as the fastener is tightened (or measure the length before and after it is tightened).
