Description

Why Choose the Long Wood Insert Nut with Hex?


Crafted with a wood-threaded exterior and an unthreaded lead section, it allows for precise alignment and secure installation in pre-drilled wood structures — supporting pull-out forces up to 4,500 kg.

Key Benefits

  • Hexagonal drive interface (Allen/hex key) enables fast and accurate installation.

  • Internal metric thread combined with robust external wood thread ensures long-lasting, heavy-duty connections in wood or panel assemblies.

  • Suitable for wood frames, stairs, lifting points and construction applications — meets CE marking CE1034 and ETA 12/0481 for usage in structural timber.

  • Available in multiple materials: standard zinc-plated steel, stainless steel 303 and stainless steel 316Ti.

Applications & Installation Guide

Typical Use Cases

  • Structural wood constructions: staircases, balustrades, facades, timber frames.

  • Scenarios where high loads, one-side access or limited space require reliable threaded anchoring.

  • Assemblies requiring hidden or flush finish for aesthetics and durability.

Step-by-Step Installation

  1. Drill the correct hole according to the insert diameter and length.

  2. Insert the threaded bushing- the unthreaded pilot section ensures proper alignment.

  3. Screw in the insert using an Allen/hex key until flush with the surface or per installation depth.

  4. Verify the installation: no tilt, full thread engagement and correct anchoring in the wood material. Perform test installations as material properties can affect performance.

  5. Fasten the component using the internal metric thread M6–M16 for your chosen bolt or screw.
