⚡ At a Glance
- • Corrosion Resistance: Zinc-plated, galvanised finish reduces surface rust and extends service life
- • Best for: DIYers, tradespeople and builders who need to conceal and protect exposed bolt threads
- • Not ideal for: Situations that require specialised high-torque fasteners or non-standard thread systems
Alloy steel construction with a zinc-plated, galvanised finish provides a strong, corrosion-resistant cap. Domed acorn heads protect exposed threads while giving a decorative finish suited to indoor and outdoor projects.
Protects threads and prevents stripping, with domed cap design
Domed acorn heads fully enclose exposed bolt threads, preventing contact and snags. Zinc-plated alloy steel adds corrosion resistance and high hardness to resist deformation.
Enclosed threads reduce the chance of thread damage and accidental catches. A neat, finished appearance removes the need for secondary covers or tape.
Durable for indoor and outdoor use, with alloy steel and galvanised finish
Alloy steel base gives higher hardness than regular steel, while the galvanised zinc plating protects surfaces against corrosion. Construction is described as heavy duty and resistant to deformation.
Longevity in exposed settings such as fencing or outdoor furniture is improved. Suitable for repeated use in typical domestic and trade environments.
Quick to fit and decorative, with standard-size geometry and triangular grip
Standard sizing and a triangular, non-isosceles grip profile aid manual handling and reduce slippage during fitting. Design aims for easy locking and a secure fit.
Faster assembly for routine jobs and a tidy finish for visible fixings. Decorative profile means no need for additional finishing caps on visible bolts.
