2. Safety Information
Always prioritize safety when working with fasteners and power tools. Failure to follow safety instructions may result in injury or damage.
- Wear appropriate personal protective equipment (PPE), including safety glasses, gloves, and hearing protection.
- Ensure the work area is well-lit and clear of obstructions.
- Use the correct size and type of driver bit for the hex head to prevent stripping.
- Do not over-tighten screws, as this can damage the timber or the screw itself.
- Keep screws out of reach of children.
- Inspect screws for any damage before use. Do not use damaged screws.
3. Product Features
The TIMCO Timber Screws are engineered with several features for optimal performance:
- 8mm Hex Head: Countersunk with a fixed washer for secure fastening and a flush finish.
- Corrosion Resistance: Patented multi-layer plating withstands up to 1,000 hours salt spray resistance (BS EN 9227:2014), suitable for exterior applications.
- Patented Lubrication: Enhances screw insertion time and further improves corrosion resistance.
- Helix Shank: Designed to remove debris during driving, improving clamping force.
- 50° Deep Single Thread: Provides a secure fixing with high pull-out resistance.
- Material: Constructed from durable carbon steel.
4. Setup and Preparation
Before installing the TIMCO Timber Screws, ensure proper preparation:
- Select Appropriate Timber: Ensure the timber is suitable for the intended application and free from significant defects.
- Choose Correct Length: Select a screw length appropriate for the thickness of the timber being joined, ensuring adequate penetration into the base material without protruding.
- Pre-drilling (Optional but Recommended): For hardwoods or to prevent splitting, pre-drilling a pilot hole slightly smaller than the screw's core diameter may be beneficial.
- Driver Bit: Use an 8mm hex driver bit that is in good condition to prevent cam-out and damage to the screw head.
5. Operating Instructions
Follow these steps for effective installation of TIMCO Timber Screws:
- Position the Screw: Place the screw tip at the desired fastening point on the timber.
- Engage Driver: Insert the 8mm hex driver bit firmly into the screw head.
- Drive the Screw: Using a suitable power drill or impact driver, apply steady, even pressure while driving the screw into the timber. Maintain a straight angle to ensure proper engagement and prevent bending.
- Secure Fastening: Continue driving until the hex head with its fixed washer is flush with the timber surface. Avoid over-tightening, which can strip the timber or shear the screw.

6. Maintenance and Storage
Proper care and storage will ensure the longevity and performance of your TIMCO Timber Screws:
- Storage: Store screws in their original packaging or a dry, cool environment to protect the corrosion-resistant coating. Avoid exposure to excessive moisture or corrosive chemicals.
- Handling: Handle screws carefully to avoid damaging the threads or coating.
- Disposal: Dispose of any damaged or unusable screws responsibly according to local regulations.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Screw head strips (cam-out) | Incorrect driver bit size; worn driver bit; insufficient pressure; excessive torque. | Use the correct 8mm hex driver bit; replace worn bits; apply firm, consistent pressure; reduce drill torque setting. |
| Screw not driving fully | Insufficient power from drill; dense timber; pilot hole too small or absent. | Use a more powerful drill/impact driver; consider pre-drilling a larger pilot hole for dense timber. |
| Timber splitting | No pilot hole; screw too close to timber edge; timber type prone to splitting. | Pre-drill a pilot hole; ensure adequate distance from timber edges; use appropriate timber for the application. |
