Nylon Insert Nuts

Nylon insert nuts, also known as nyloc nuts. Available in various diameters and materials at competitive prices. Available as standard or a high-type, with the high-type being a slightly bigger nut. A hexagonal nut that includes an internal nylon collar which increases friction on the screw. This increases the tightening pressure and allows for a firmer hold. Ideal in situations where vibration and motion are a factor and effective against the ingress of liquids like oil, water, and petrol.

Supplied in various materials and diameters all at competitive prices, with an extensive range of bolts also available.

What is a nylon insert nut?

A nylon insert nut, also known as a nyloc nut, is a type of mechanical fastener manufactured from several different materials. The nuts come in various diameters and threads to accommodate the wealth of requirements across many industries.

The nylon insert nut is like many of the hex nuts on the market but is supplied with an internal nylon insert. The nylon insert presses against the bolt and  increases the tightening pressure allowing for a firmer hold. Like many other hex nuts, it is almost always used in conjunction with a bolt which carries the same thread.

Available in two types which includes a ‘T’ type and a ‘P’ type. Both are generally the same but the ‘P’ type has a little thicker insert and allows for more of a firmer hold.

Please be aware - They can not be used in high-temperature applications as the Nylon insert would melt.

What are nyloc nuts used for?

Like many other nuts the nylon insert nut is used in conjunction with bolts to tighten separate sheets of material together. There is an added advantage with the nyloc nut, as the insert also helps in sealing the bolt against the ingress of various liquids like oil, water, and petrol.

What are nylon insert nuts made from?

The nylon insert nuts here at Fusion Fixings are manufactured from various materials including  A2 / A4 stainless steel, steel with BZP - bright zinc plated, brass, self-colour steel and hot dip galvanised steel. All have their own properties, but the combination of these materials covers a range of requirements across many industries.
