➤SKIP TO: HEX NUTS | LOCK NUTS | STAMPED NUTS

General Description: Nuts are fasteners which have an internally threaded hole. They are normally used with screws or bolts in mechanical assemblies to fasten two or more parts together. Nuts can be manufactured by various processes; the most typical are cold forming, screw machining (turning) and stamping.

Hex Nuts

Hex nuts include various “patterns” which designate the distance across the flats (AF) as well as the thickness (height). Typically these would be: machine screw nut, finished hex nut, jam nut, heavy hex nut, and so on. Coupling nuts are extra long (thick) nuts that are used to couple at each end. Nuts have become very standardized and are generally available off the shelf. Customization is possible so that the design is optimal for a specific application. Inch nuts are governed by the SAE J995 standard. Metric nuts are governed by the ISO 898 standard.

MATERIAL OPTIONS: Steel (with appropriate property classes for use with designated bolts), Various Stainless Steels and Brass

PLATING OPTIONS: Plating varieties are endless and can be determined according to the application. Zinc is the most common and cost effective.

Lock Nuts

Many assembly applications are subject to vibration and loosening of the joint. In such cases, locknuts should be used. Several secondary methods are employed to create the lock, including: serrated flange, top lock, side lock, elliptical lock, nylon insert, and nylon adhesive patch. Nuts can also be preassembled to lockwashers (Keps) and conical spring washers. Customization is possible so that the design is optimal for a specific application. Inch nuts are governed by the SAE J995 standard. Metric nuts are governed by the ISO 898 standard.

Stamped Nuts

Some parts are made for basic applications where strengths and locking are of less concern, but available space or appearance are required. Cap nuts with an acorn shape offer an attractive look. Panel nuts, cage nuts, wing and tee nuts are also stamped and provide a low cost alternatives to CNC machining. Customization is possible so that the design is optimal for a specific application.
