WASHERS
PLAIN WASHERS
Plain washers, which spread a load, and prevent damage to the surface being fixed, or provide some sort of insulation such as electrical. Spring washers, which have axial flexibility and are used to prevent fastening or loosening due to vibrations.
BELLEVILLE WASHER
A Belleville washer is a cone-shaped disc spring, also called a disc spring, that can apply a high load with minimal deflection and is used to solve problems like vibration, thermal expansion, and bolt creep. These washers can be stacked in series, parallel, or a combination to alter the total load and deflection of the stack for a specific application.
GRIP WASHER
A grip washer is a type of washer designed to prevent fasteners from loosening due to vibration or stress. It achieves this by using a surface texture, such as radial ribs or serrations, to bite into both the bolt head and the material being fastened, creating a secure, high-friction lock. This design is especially effective in high-stress applications and provides more holding power than a standard washer.
FENDER WASHER
A fender washer is a type of flat washer with a significantly larger outer diameter than its central hole. Its primary purpose is to distribute the pressure of a fastener, such as a bolt or screw, over a wider area. This prevents the fastener from damaging the surface it's being attached to, making them ideal for use on soft materials, sheet metal, or in applications where a hole may have been enlarged over time.
TAIPER WASHER
A taper washer is a washer with a sloping or angled surface, designed to compensate for non-parallel surfaces in structural applications. They are used to ensure a bolt and nut assembly creates a square, stable connection when tightening against angled flanges on structures like I-beams, channels, and structural steel. Taper washers create a flush and even load distribution, which prevents the bolt from bending or becoming fatigued
SPRING WASHER
Spring washers are used to prevent fasteners from loosening due to vibration or shock, absorb dynamic loads, and compensate for expansion and contraction. They work by applying continuous tension to a joint, often by digging into the surfaces of the nut and bolt, or by acting as a spring to absorb energy. They are essential in applications like automotive, aerospace, and heavy machinery to maintain assembly integrity and enhance safety.
