M48 x 145mm - Telescopic Thread Protection Nut and Washer Caps DIN 125 - LDPE - Black | Vital Parts - TPNWC-M48-145-T-B

Our Telescopic Thread Protection Nut and Washer Caps are an efficient solution for protecting long bolt projections and exposed threads in demanding environments. Designed to snap easily onto nuts and fully cover washers, these caps offer both functional and aesthetic benefits for industrial, construction, and marine applications.

What are Telescopic Thread Protection Nut and Washer Caps?

Also known as Nut Caps, Bolt Caps, or Washer Caps, these components are made from high-quality LDPE and are specifically designed to cover nuts, washers, and extended bolt threads. The telescopic design allows a single cap to fit a range of stud lengths, eliminating the need for multiple cap sizes and reducing inventory waste. They feature a clamping edge that secures beneath the chamfer of the nut, while internal ribs deform upon installation to increase grip strength-delivering a secure, vibration-resistant fit in any setting.

Key Features:

• Made from durable LDPE with excellent chemical resistance
• Telescopic structure accommodates a range of bolt lengths
• Snaps onto hex nuts and fully covers the washer
• Clamping edge and internal ribs ensure a firm, secure fit
• Low electrical conductivity for added workplace safety
• Available in sizes from M4 to M90
