M12 x 1.25, Tapered seat, 17 Hex, H/Socket, Galv

A heavy-duty wheel nut with M12 × 1.25 thread and 60° tapered seat, featuring an internal hex (H-socket) design for recessed wheel applications. The galvanised zinc coating provides excellent corrosion protection for UK road conditions, while the compact profile suits wheels with limited clearance around the fixing points.

Quick Specs

• Thread/Seat: M12 × 1.25 with 60° conical taper for secure wheel contact
• Hex Size: 17mm across flats (standard socket compatible)
• Design: H-socket (internal hex) configuration for recessed wheel bolt holes
• Thread Length: 22mm shank for proper hub engagement
• Finish: Hot-dip galvanised zinc coating for long-lasting rust protection
• Material: Forged Grade 10.9 high-tensile carbon steel

What Makes It Different

The H-socket (internal hex) design allows this nut to sit deeper in recessed wheel mounting holes, providing a flush appearance while maintaining full thread engagement. This is particularly useful for aftermarket wheels with decorative covers or where external hex nuts would protrude.
