Used to join a larger diameter threaded rod to a smaller diameter threaded rod. A coupling nut, also known as extension nut, is a threaded fastener for joining two male threads, most commonly a threaded rod, but also pipes

Used to join two externally threaded parts of equal thread diameter and pitch, often two pieces of threaded rod

Designed to be used with like-material machine screws and bolts. It is able to be reused more times than a two-way reversible nut. Steel nylon insert stop nuts are less expensive than grade-C automation lock nuts. However, nylon will begin to deteriorate at temperatures from 150˚-350˚ F

Steel: #2 through 5/8” -- AISI 1008 - 1010 or equivalent steel; 3/4 through 1-1/2”-- AISI C1117 or equivalent steel

Steel: AISI 1006 - 1022 or equivalent steel.: Steel: 60,000 psi. minimum. Rockwell B70 - B100

Stainless: 18-8 stainless. Stainless: 100,000 - 125,000 psi. (approximate). Stainless: 1/4 through 1/2 in. diameter-- Rockwell B95 - C32

A two-piece fastening system consisting of (1) a self-contained pin within (2) the body of a tubular-shaped rivet with a flat, countersunk head. The head is countersunk at an angle of 100° and is a little less than twice th e diameter of the shank. The top of the rivet has an opening through which the pin protrudes. The opposite end of the rivet is enclosed but with two cross-wise slits cut into the body extendin g from the tip, up the shank a limited distance.

Drive pin rivets can join two or more pieces of low-density metal without the use of special installation tools. The rivet is inserted into pre-drilled, aligned holes and is set in place by striking the top of the pin with a hammer so that the pin is flus

An externally threaded fastener without a head that is threaded over its entire length

Used in manufacturing, plumbing and construction industries. Can serve to reinforce base structures by installing stud into a metal surface and securing it with a nut at the opposite end of the stud.

The “Small Pan” head machine screw per JIS-B1111 is a preferred design for use in small electronic components where there is limited clearance area. The M3 and M4 diameters also meet the requirements of SN 213307 Cheese head screws.

Class 4.8 machine screws shall be made from a carbon steel, partially or fully annealed as required, which conforms to the following chemical composition-- Carbon: 0.55% maximum; Phosphorus: 0.05% maximum; Sulfur: 0.06% maximum.

Can be used in ceilling, hollow walls, steel, concrete or wood. Requires smaller holes than toogle bolts. Applications include overhead doors, light fixtures, shelf brackets and cable television units

Carbon steel

Primary use for Class 10.9 bolt is on truck cassis frames. The flange eliminates the need for a flat washer and helps compensate for a misaligned hole. When used with a proper class flange nut, the bolt system resists bolt slippage by distributing the clamp load over a wide area

Class 8.8 carbon steel chemical composition: Carbon- 0.15 - 0.55%; Phosphorous- 0.35% max; Sulphur- 0.35% max
