Plastic Hexagon Half Nuts

Plastic Hexagon Half Nuts are often referred to as Nylon Hex Flat Nuts, Thin Nuts, Jam Nuts or Locknuts. As the name suggests, they are roughly half the height of a standard Hexagon Full Nut, found in a wide range of applications and assemblies.

Typically used in pairs and positioned either side of a standard nut to prevent self-loosening and keep it locked in place. They are also ideal for applications with limited clearance where a standard size nut would not otherwise fit. Plastic Hexagon Full Nuts are also available at Fastenright.

Manufactured from Nylon 66 (PA 66) as standard, helping to create a strong, lightweight fastener that is resistant to corrosion and rust. Black Nylon 30% Glass Filled Flat Nuts are also available, with other types of plastic available on request.

Supplied in a Black finish as standard, these Nylon Hex Thin Nuts can by dyed to colour match the intended application or assembly.

Available in thread sizes from M6 to M40 as standard, with special Plastic Hexagon Half Nuts available to order. Minimum order quantities apply.

Non-standard sizes, materials and colours are available to order as specials, including small volume manufacture, modifications and custom parts made to drawings.
