Sheet Metal Nuts & Strips

Push-On Nuts, Rectangular Push-On Nuts, Rectangular Shaft Retainer

Definition: Push-on nuts are designed for the stud or shaft retainers to engage an unthreaded or threaded stud or shaft on two sides. Notched springs deflect to encompass the stud as the retainer is pushed on, setting up a strong strut action that resists any back-off pressure. Push-on nuts are designed for quick, usually permanent assembly, unless used with a “D” shaped stud. They are a time and labor saving component.

Push-On Nuts are available in the following materials and finishes:

  • Spring Steel: Black Oxide, Cadmium types I & II, Chrome, Degreasing, Bright Nickel, Pickling, Silver, Bright Tin, Hot Tin Dip, and Zinc types I & II

Formed Sheet Metal Nut, Speed Nut, Clip-on Nut

Definition: Formed sheet metal nuts are also known as speed nuts or clip-on nuts. Speed nuts are designed with two sheet metal prongs that act as one thread which provides a full 360° grip. As the machine or sheet metal screw is tightened the prongs are drawn inward until they exert pressure on the root of the thread on the screw. As the screw is tightened, the base of the nut flattens and applies enough force to the screw that it keeps it from loosening under vibration. They are a form of locknut which serves the functions of both lock washers and nuts, saving assembly time and money.

Formed Sheet Metal Nuts are available in the following materials and finishes:

  • Cold Rolled Steel (Steel): Black Oxide, Cadmium types I & II, Chrome, Degreasing, Bright Nickel, Pickling, Phosphate, Silver, Bright Tin, Hot Tin Dip, and Zinc types I & II

Formed Sheet Metal Nut: 2720

Formed Sheet Metal Strip

Definition: Formed sheet metal strips are similar to formed sheet metal nuts or speed nuts, however, they are available in strip form with multiple holes of variable thread size and spacing. Formed sheet metal strips become their own fastening element by eliminating the use of nuts or washers. The elimination of extra parts substantially cuts assembly labor cost and time.

Formed Sheet Metal Strips are available in the following materials and finishes:

  • Cold Rolled Steel (Steel): Black Oxide, Cadmium types I & II, Chrome, Degreasing, Bright Nickel, Pickling, Phosphate, Silver, Bright Tin, Hot Tin Dip, and Zinc types I & II

Formed Sheet Metal Strip: 2705

Example: Formed Sheet Metal Strip



Threaded Sheet Metal Strips, Tapped Sheet Metal Strips

Definition: Threaded sheet metal strips become their own fastening element by eliminating the use of nuts or washers. They are used with machine screws. The tapped sheet metal strips are available with multiple holes of variable thread size and spacing. The elimination of extra parts substantially cuts assembly labor cost and time.

Threaded Sheet Metal Strips are available in the following materials and finishes:

  • Cold Rolled Steel (Steel): Black Oxide, Cadmium types I & II, Chrome, Degreasing, Bright Nickel, Pickling, Phosphate, Silver, Bright Tin, Hot Tin Dip, and Zinc types I & II

Threaded Sheet Metal Strip: 2706
