Lock Nut

• A jam nut, also known as a thin hex nut, is a low-profile nut typically used as a locking mechanism against another standard nut.

• It is tightened against the main nut to prevent loosening caused by vibration or torque.

• Jam nuts are often used in double-nut locking arrangements, electrical components, and tight-clearance applications.

Nylon Insert Lock Nut

• A nylon insert lock nut, or Nyloc nut, features a nylon ring at the top of the nut. This ring deforms as the nut is tightened, gripping the bolt threads and creating a frictional force that resists loosening due to vibration or movement.

• These nuts are commonly used in automotive, aerospace, and machinery applications. The nylon insert also helps seal out moisture.

WASHER

Flat Washer

• A flat washer is a thin, round disk with a hole in the center, typically made from metal or plastic. It is used to distribute the load of a threaded fastener

• Flat washers also help to prevent loosening in vibrating environments and can provide spacing or insulation. Commonly used in construction, automotive, machinery,

Star Washer

• A star washer, specifically an internal tooth lock washer, features multiple teeth pointing inward from the inner edge. These teeth bite into the surface of the connected material and the mating fastener (like a screw or bolt)

• Star washers are often used in electrical applications, automotive assemblies, and metal fastenings where a more secure grip is required.

Spring Washer

• A spring washer is a type of lock washer made of metal and split at one point with a slight curve or twist.

• It is designed to exert a spring force between the head of the bolt and the substrate, maintaining tension and preventing loosening due to vibration or torque.

• Common Use: Machinery, automotive, and electrical applications

Plain Washers

• A plain washer is a flat, circular metal disc with a central hole. It is typically placed between a fastener (like a bolt or screw)

• And the surface it's securing to distribute the load of the fastener, reduce friction, prevent leakage, and protect the surface from damage.
