Description
Overview:
The Cup Square Head Coach Bolts, Zinc Plated, M8 x 25 mm, are robust fasteners for wood-to-metal and wood-to-wood joints in construction, landscaping, and workshop tasks. Made from steel with a bright zinc-plated finish, they resist rust and surface wear, making them suitable for indoor and outdoor use. The domed cup head with square neck locks into timber to prevent spinning while the nut is tightened, giving a neat, low-profile finish on the outer face. At 25 mm long (approx. 0.98 inches) and M8 diameter (approx. 0.31 inches), they suit fixtures where a short, strong fixing is required. Supplied in a practical pack of 50 to support repeatable, consistent assembly across fencing, gates, furniture builds, and machinery guarding.
Key Features:
- M8 x 25 mm size (approx. 0.31 x 0.98 inches) for compact, high-strength fixings
- Steel construction with zinc plating for corrosion resistance in UK weather
- Cup (domed) head and square neck to stop rotation in timber during tightening
- Clean, rolled metric thread for smooth engagement with standard M8 nuts
- Neat, snag-resistant head for a tidy finish on visible faces
- Pack of 50 for consistent assembly and convenient stockholding
- Suitable for wood-to-metal joints when paired with washers and M8 nuts (not included)
- Reliable clamping where through-bolting is preferred over screws
- Compatible with hand tools or power drivers using an M8 nut and spanner/socket
- Manufacturer reference: MPN 903 0259 for easy identification
Typical Applications:
Used for decking subframes, garden gates, fencing rails, sleepers, benches, and site hoarding. Common in sheds, pergolas, trailers, pallet and crate assembly, machinery guards, and general woodwork where a through-bolt offers stronger, longer-lasting joints than screws. Ideal for repairs and new builds in construction and landscaping.
