What are the differences between a hex cap screw and a hex machine bolt?These terms are often incorrectly used interchangeably. The most basic difference between a cap screw and a machine bolt is the way in which these fasteners are installed. Technically, a machine bolt is installed by turning a nu

The welding nut is a nut suitable for welding outside the nut. It is generally made of weldable materials and is suitable for welding. Welding is equivalent to two separate parts into a whole, with a high temperature metal melt together and then cooling, in the middle will join alloy, internal is a function of molecular force, intensity is generally larger than the maternal strength.

Spring washers have a small footprint and are valued in small machines where a coil spring would be unsuitable. Spring washers can also deflect in a linear, progressive, or regressive means and these devices show a symmetrical deflection around the washer's axis. Spring washers can be stacked to create spring sets or series where deflection and load capacity can vary without materially affecting the forces involved.

In the requirements analysis phase, the specification can help specify the customer's vague requirements, and identify the conflicting, ambiguous, and unstated requirements. Hardware fastener industry even more so, the specifications of the products size are different, Jiaxing Goshen hardware's offe

A nylon insert lock nut, also referred to as a nyloc nut, polymer-insert lock nut, or nylon insert (elastic) stop nut, is a common type of lock nut comprised of a hex nut with a fixed nylon-filled collar at its back end. When a screw reaches the collar, the threads and nylon form a tight, frictional fit, thus restricting movement of the screw when it is subject to vibration. Nyloc nuts are designed to be used with machine screws and bolts and can be reused.

Castle nuts are just one type of hardware commonly used in mechanics. Also known as castellated nuts, a castle nut is characterized by the notches present on one end, which resemble the serrated tops of castle parapets. The accompanying bolt has typically one to two holes, which allows the nut to lock securely in place.
