JM Hardware® carriage bolt has a square shoulder under a rounded head which resists turning when the nut is tightened or removed. They are good for wood-to-wood connections when the head may not be accessible for tightening. They may be used in the construction of docks, swing sets and decks as well as other surfaces where a smooth finish is needed.

Depending on the part’s shape and requirements custom machined parts might be made on a lathe, a milling machine, a stamping press, a press-brake, a precision shear, or machined on a myriad of other types of precision equipment. In many cases a custom machined part might pass through many of the operations listed before being finished. Although custom machined parts are typically more expensive than a mass-produced method, quite often the higher price is justified due to the fact that custom machined parts are generally more accurate, offer higher strength and/or integrity and can be made much faster than most other methods.

Coupling nuts, also known as extension nuts, are threaded fasteners used for joining two male threaded rods. The exterior of this fastener is typically a hex so a wrench can hold it easily. We offer a variety of stainless steel coupling nuts in a range of sizes.Rod Coupling Nuts are used to join two externally threaded objects, usually threaded rod, together. Reducing Coupling Nuts are available to couple two or more studs of different diameters together.

Split lock washers, also known as spring lock washers,  are designed with a split at one point and bent into a helical shape. This causes the washer to exert a spring force between the fastener’s head and the substrate, creating more friction and resistance to rotation.Lock washers are specially designed to keep threaded fasteners from loosening. They prevent vibrations and some have external teeth to prevent rotation. These washers are often found in airplanes and in structural applications.
