Product Title

Heavy-Duty Hex Head Coach Screw / Lag Bolt – Zinc Plated Steel

Product Overview

This Hex Head Coach Screw is a robust fastener designed for applications where high torque and superior holding power are required. Featuring a heavy-duty hexagonal head for secure wrenching and a sharp, deep-threaded point for wood penetration, it is the standard choice for structural timber work and masonry anchoring (when used with a wall plug).

Key Features

High-Torque Hex Head: The six-sided head allows for maximum leverage using a wrench or socket, ensuring a tight, secure fit even in dense materials.
Aggressive Wood Thread: Features deep, spaced threads designed to bite into timber, providing excellent resistance to pull-out.
Gimlet Point: The sharp, tapered tip allows for easier starting and centered alignment during installation.
Zinc Plated Finish: Coated in a bright zinc finish to provide a layer of protection against corrosion and oxidation, making it suitable for indoor and sheltered outdoor use.
Versatile Anchoring: While primarily used for wood-to-wood connections, it can also be used in masonry or concrete when paired with an appropriately sized expansion plug.

Installation Tips

Pilot Hole: To prevent timber splitting and ensure easier driving, always drill a pilot hole approximately 70% to 80% of the screw’s shank diameter.
Lubrication: For very hard woods, applying a small amount of wax or soap to the threads can reduce friction.
Wrench Drive: Use a correctly sized socket or spanner to avoid rounding off the hex head corners.
