Carpenters Mate Pro Hex Head Screws - 6.3 x 90mm - 250 Pk

Yes, these screws are designed for structural timber applications, including treated timber used in framing and outdoor construction. The advanced coating provides protection.

Carpenters Mate offers a comprehensive project replacement guarantee if a proven screw failure occurs due to a manufacturing fault.

These are hex head screws. You will need a compatible hex drive tool or socket bit, typically for a power drill or impact driver, matching the size of the hex head.

While they offer superior strength, they are specifically engineered as structural replacements for M10 coach bolts. For lighter-duty tasks, they might be more than necessary, but they will certainly provide a very strong fastening.

The structural rating is stamped directly onto the head of each screw, making it easily visible for compliance and quality assurance checks.

No, these are screws designed to be driven directly into timber. Pre-drilling a pilot hole is recommended, especially in dense hardwoods, to prevent timber splitting and ease installation.

The screws are manufactured from high-strength carbon steel with a unique case-hardened coating.

Ensure you are using the correct size and type of drive tool. Apply firm, consistent pressure directly into the screw head. If driving into hardwood, pre-drilling an appropriate pilot hole can reduce strain.

Check if a pilot hole is needed for the timber type and depth. Ensure no obstructions are present in the timber or screw hole. Verify the screw is perpendicular to the timber surface.

While coated for lifetime performance, extreme environmental conditions could affect the coating over extended periods. Contact Carpenters Mate customer support if you suspect a coating failure related to the guarantee.
