Hex Lag Screw Niczuk M10x60 — 6-sided head, metric M10 x 60 mm

Hex lag screw Niczuk M10x60 — 6-sided head, metric M10 x 60 mm is a heavy-duty wood and construction fastener designed for creating strong threaded connections in timber. The fastener features a hexagonal head sized for standard M10 sockets or wrenches and a 60 mm threaded shank that provides deep engagement in beams, posts and other structural wooden elements. Use with an appropriate pilot hole to prevent splitting and ensure correct seating of the hex head.

Advantages

The Niczuk M10x60 hex lag screw delivers high clamp force and reliable withdrawal resistance thanks to its full threaded shank and metric M10 diameter. The 6-sided head allows for easy torque application with sockets or wrenches, enabling tight and repeatable fastening. Its length and thread form are suitable for heavy timber fixtures, providing stable connections in structural and outdoor applications when used with compatible materials and treatment.

Suitable for

• Securing beams and joists in timber framing
• Attaching posts, railings and fence fixtures
• Mounting heavy wooden fixtures and brackets
• General structural fastening in carpentry and construction

Key specifications

• Thread diameter: M10 (metric)
• Overall length: 60 mm
• Head type: 6-sided (hex) head compatible with M10 sockets/wrenches
• Material and finish: suitable for structural use (refer to supplier for specific coating)
• Designed for use with pilot holes in wood

How to use

Drill a pilot hole appropriate to the timber species and the M10 diameter to minimize splitting and to allow full thread engagement. Position the hex lag screw and tighten using an appropriately sized socket, wrench or impact driver with a hex socket, applying steady torque until the head seats flush or to the required clamp level. For through connections or very dense hardwoods, consider countersinking the head or pre-drilling a larger clearance hole for the shank as needed.

Usage recommendations

Use corrosion-resistant or coated variants for outdoor or treated timber applications. Select pilot hole diameter and fastening torque according to wood density and structural load requirements. Where code or engineering specifications apply, follow prescribed spacings, edge distances and load ratings.
