⚡ At a Glance
- • Protection Quality: Corrosion and UV resistant PE construction keeps threads dry and clean
- • Best for: Outdoor fixtures, machinery and pipework where fasteners face weather exposure
- • Not ideal for: Non-hex or oversized fasteners and situations requiring unrestricted wrench access
Pack contains approximately 20 PE caps sized for M6 hex nuts and bolt heads. The caps are corrosion and UV resistant with a snug hex internal shape for a secure fit.
Rust and weather protection – thanks to PE plastic construction
High-quality PE plastic resists corrosion, ultraviolet degradation and low-temperature ageing, forming a physical barrier over bolt heads. The material remains flexible yet tough so caps do not deform easily.
Keeping water and dust away from threads reduces corrosion risk and extends fastener life. Suitable for repeated outdoor exposure without rapid deterioration.
Safer, neater finish – with domed hexagonal caps
A domed profile covers sharp bolt ends while the internal hexagonal profile matches nut heads for a close fit. The external finish tidies visible fixings on structures and equipment.
Covers exposed threads to prevent cuts and snags while improving appearance on street furniture, railings and visible machinery. Handy where a finished look matters.
Quick fit and removal – with sized M6 fit compatible with 10mm spanner
Designed for M6 hexagon-shaped bolts and nuts, referenced with a 10mm spanner size for installation and removal. The snug internal shape holds caps in place under light vibration.
Fast to fit during installation and simple to remove for maintenance using basic tools. Secure seating reduces chances of caps falling off in normal outdoor conditions.
