Threadall Manufacturing - Washers and Plates

By: Threadall  09-12-2011

A washer is a thin plate (typically disk-shaped) with a hole (typically in the middle) that is normally used to distribute the load of a threaded fastener, such as a screw or nut. Other uses are as a spacer, spring (belleville washer, wave washer), wear pad, preload indicating device, locking device, and to reduce vibration (rubber washer). Washers usually have an outer diameter (OD) about twice the length of their inner diameter (ID).*

Threadall Manufacturing - Bolts

A screw is an externally threaded fastener capable of being inserted into holes in assembled parts, of mating with a preformed internal thread or forming its own thread, and of being tightened or released by torquing the head. A bolt is an externally threaded fastener designed for insertion through holes in assembled parts, and is normally intended to be tightened or released by torquing a nut. Round head bolts, track bolts, plow bolts..


Threadall Manufacturing - Heading and Bending

Bending is a manufacturing process that produces a V-shape, U-shape, or channel shape along a straight axis in ductile materials. Cold forming techniques are usually classified into four major groups: squeezing, bending, drawing, and shearing. Examples of applications include the heading of bolts and cap screws and the finishing of cold rolled steel*. Threadall Manufacturing Heading Capabilities Include. Long Lengths and Special Heads.


Threadall Manufacturing - Rods and Studs

A threaded rod, also known as a stud, is a relatively long rod that is threaded on both ends; the thread may extend along the complete length of the rod. Full bodied studs (Cut Thread) are weaker because metal is removed to create the thread, disturbing the grain of the steel. For studs that are not completely threaded, there are two types of studs: full-bodied studs, and undercut studs.


Threadall Manufacturing - Nuts

The most common shape is hexagonal, for similar reasons as the bolt head - 6 sides give a good granularity of angles for a tool to approach from, but more corners would be vulnerable to being rounded off. The two partners are kept together by a combination of their threads' friction, a slight stretch of the bolt, and compression of the parts. Nuts are almost always used opposite a mating bolt to fasten a stack of parts together.


Threadall Manufacturing - Thread Rolling / Thread Cutting

Rolled threads are stronger than cut threads, with increases of 10% to 20% in tensile strength and possibly more in fatigue resistance and wear resistance. Threads of metal fasteners are usually created on a thread rolling machine. Threading capabilities at Threadall Manufacturing Include. They may also be cut with a lathe, tap or die.
