Plastic Nuts & Bolts are displayed below. Great for use in corrosive environments and where metallic or magnetic fasteners can not be used. Available in most of the common forms of fastener, Hexagon Het Screw, Cap Heads and Slotted Machine screws with nuts and washers to match.
Nylon (polyamide) - a tough lightweight plastic, tough at low temperaures, with excellent resistance to chemicals and features a favourable sliding friction behaviour.
The most common type of fastener, a hex head bolt is designed to be tightened with a standard spanner or ratchet and socket. Popularly used in all assemblies, a standard hex bolt is a staple across the world. Manufactured to ISO 4014 or DIN 931, and therefore includes an unthreaded section of the shaft. A hex drive permits a greater torque load to be applied to the joint over most other drive types.
Commonly referred to as a setscrew or simply as a bolt. The fully threaded ISO 4017 or DIN 933 should not be confused with it's DIN 931 equivalent. A standard spanner or ratchet is typically used to fit this product. Used for decades on all types of assembly throughout the world. As with the DIN 931 hex bolt, the hex drive allows a higher torque to be applied.
Hexagon full nut to DIN standard 934 with standard metric coarse pitch. Typically fitted with a spanner or ratchet with socket. The most popular nut type, and used for decades on all types of assemblies throughout the world. Can be used in conjunction with Hexagon Thin nuts in a 'locking' formation for a more secure fitment. Fine pitch and left hand thread variants are also available immediately below this item.
Form A Washers ISO 7089 non chamfer & 7090 chamfered (DIN 125A)
A standard flat washer for use in just about any assembly. A flat washer's main task is to spread the load across a wider area, which comes in particularly useful when dealing with softer materials. Conforms to DIN 125.
Also known as an Allen screw or Allen bolt, or simply a cap screw. Socket Head Cap screws are a more modern alternative standard machine fastener to the standard hexagon headed bolt or setscrew, as found on much modern machinery. A hex key (otherwise known as an Allen key) is required to fit these fasteners. Conforming to DIN 912 or ISO 4762.
An hexagon nut with incorporated flange, to DIN 6923. The flange offers protection for the bolted component where the driving tool may otherwise scratch it's surface. The flange also lessens the need to use a washer. This particular version is non-serrated on the base. A serrated variant is also available.
