Partial Threaded Bolt Middle Thread Tip End Pan Cross Head

Partial threaded bolt is the bolt with a part of thread in the body. It is different from the normal partial threaded bolt, the thread is on the middle of the body. Ever Hardware provides custom-made fasteners and customizable packaging.

Tip end makes the partial threaded bolt suitable for machine assembly. A screw thread, often shortened to thread, is a helical structure used to convert between rotational and linear movement or force. A screw thread is a ridge wrapped around a cylinder or cone in the form of a helix, with the former being called a straight thread and the latter called a tapered thread. A screw thread is the essential feature of the screw as a simple machine and also as a fastener.
The mechanical advantage of a screw thread depends on its lead, which is the linear distance the screw travels in one revolution.

Cross also known as phillips. The Phillips screw drive was created by John P. Thompson, who after failing to interest manufacturers, sold his design to businessman Henry F. Phillips. Phillips is credited with forming a company (Phillips Screw Company), improving the design, and promoting the adoption of his product. The original patent expired in 1966, but the Phillips Screw Company continued to develop improved designs.
Phillips drive bits are often designated by the letters “PH”, plus a size code 0000, 000, 00, 0, 1, 2, 3, or 4 (by order of increasing size); the numerical bit size codes do not necessarily correspond to nominal screw size numbers.
