This 10mm x 75mm hex head coach screw (lag bolt) is manufactured to DIN 571 in A2 stainless steel (304 grade). DIN 571 specifies a large hex head with a coarse wood-screw thread and gimlet point, driven with a spanner or socket rather than a screwdriver. The coarse thread provides high pull-out resistance in softwood and hardwood alike - making this the standard heavy-duty fastener for structural timber connections, post bases, brackets, and large landscaping projects. A clearance hole slightly larger than the plain shank diameter should be pre-drilled before installation.

Typical applications

  • Timber-to-timber and timber-to-steel structural connections
  • Fence posts, gate frames, and agricultural timber work
  • Garden structures, pergolas, and heavy-duty outdoor joinery
  • Structural brackets, deck support posts, and landscape timber fixings

Available in packs of 10 to 50, with free next-day UK delivery on orders over £50 and 30-day no-quibble returns.
