Home improvement fasteners designed for lightweight, corrosion-resistant assemblies that keep joins neat and non-conductive. Meet Caterpillar Red Nylon Fastener Kit, a 150-piece set that helps DIYers and small installers achieve secure, rust-free joins with minimal fuss. Are M4 x 40mm nylon bolts the right choice for the jobs you usually tackle?
⚡ At a Glance
- • Durability: High strength-to-weight ratio, resistant to many solvents, fuels, oils and weak acids/bases
- • Best for: DIYers, hobbyists and light installers needing non-corrosive, electrically insulating fixings
- • Not ideal for: Heavy structural or load-bearing metalwork
A kit of 50 M4 x 40mm pan-head crosshead bolts with matching nuts and washers, made from PA66 nylon. Suitable where corrosion resistance and electrical insulation are required.
Corrosion resistance - thanks to PA66 nylon construction
PA66 (polyamide 66) offers chemical resistance to many organic solvents, fuels, oils and weak acids and bases, which slows material degradation. The polymer’s intrinsic non-metallic nature prevents oxidation and rust formation.
Corrosion resistance keeps fixings intact in damp or chemically exposed environments, reducing the need for frequent replacement and maintenance.
Safe for electrical work - with electrical insulating nylon
Nylon is an electrical insulator and does not create conductive paths between joined parts. The insulating property is inherent to the PA66 material.
Makes fastening near wiring and small electronics safer by reducing the risk of short circuits and stray conduction.
Quick, consistent assembly - with pan head crosshead bolts (M4 x 40mm)
Pan head geometry spreads load across the seating surface while the crosshead drive accepts standard crosshead screwdrivers; M4 sizing with 0.7mm pitch matches common metric fittings. Matched nuts and washers ensure repeatable thread engagement.
Straightforward assembly with a crosshead screwdriver yields consistent, secure joins across multiple fixings, ideal for repeated tasks or batch installations.
