Description
Overview:
The Coach Bolt & Nut M10 x 40mm Zinc Plated for Wall Fixing is a cup square (mushroom head, square neck) bolt set made from zinc-plated steel for dependable fastening in construction, maintenance, and general wall fixing. The smooth domed head sits neatly on the outside face, while the square neck bites into the material to stop the bolt turning as you tighten the nut. At M10 x 40 mm (approx. 0.39 x 1.57 inches), it suits medium-duty fixings such as securing timber battens, brackets, plates, guards, and frames to walls or steelwork. Use with suitable wall plugs, anchors, or through-bolts when fixing to masonry. The zinc plating resists rust, and the set conforms to BS 4933 for quality assurance. Supplied with a matching M10 hex nut.
Key Features:
- M10 x 40 mm size (approx. 0.39 x 1.57 inches) for versatile, medium-duty fixings
- Cup square head with square neck prevents rotation during tightening
- Smooth, low-profile mushroom head for a neat, low-snag finish and basic tamper resistance
- Zinc-plated (BZP) steel for reliable corrosion resistance in everyday conditions
- Supplied with M10 hex nut; tighten from the nut side for quick, safe installation
- Suitable for timber-to-timber, timber-to-steel, and timber-to-masonry (with appropriate anchors)
- Works well for brackets, plates, guards, frames, and fixtures on site or in the workshop
- Conforms to BS 4933 for quality and dimensional consistency
- Common, readily serviceable size with standard spanner/socket tools (M10 nut typically 17 mm AF)
- Short 40 mm length helps avoid excess protrusion where space behind the fixture is limited
Typical Applications:
Securing timber battens to walls with plugs, fixing steel or angle brackets, mounting machinery guards or covers to frames, installing fencing rails and gates, attaching signage and plates, and assembling jigs or benches. Suitable for building sites, workshops, farms, landscaping, and general maintenance where a neat, non-turning head is preferred.
