Standard Thread Protection Nut and Washer Caps DIN 125

Our Standard Thread Protection Nut and Washer Caps, which are also known as Washer Caps, Nut Caps or Bolt Caps, are made from high quality LDPE which is highly resistant.

Standard Thread Protection Nut and Washer Caps are specifically designed for use with hexagonal nuts or screw heads, or for use with screw connections that do not require washers. They aim to offer protection to the otherwise exposed threads from dirt, damage, corrosion or injury.

These caps feature a clamping edge which grips underneath the chamfer on the nut and provides a strong connection. They also feature internal ribs which deform when inserted onto the nut, which further increase the clamping effect of the caps.

Our Standard range is suitable for threads from M4 to M90 and are available in a variety of size ranges. We also stock Telescopic Protection Nut and Washer Caps which are suitable for applications which feature long bolt projections.

Our Standard Thread Protection Nut and Washer Caps are stocked in black LDPE as standard, however we can offer custom batches in any RAL colour as required.

Please Note: We do not recommend using our Standard Thread Protection Nut and Washer Caps in conjunction with Lock Nuts.
