Extended Product Information
FAQs
What is timber jacking?
Timber jacking is a phenomenon where a screw pushes timber members apart as it's driven, compromising the connection's integrity. The TIMco TX40 C2 screws are engineered to prevent this.
What size is the TX drive recess?
The drive recess is a TX40 Torx size, requiring a compatible bit for installation.
How does the lubricant coating help?
The high-molecular polymer lubricant coating reduces insertion torque by up to 52%, making driving easier and faster, and also enhances the screw's resistance to rust.
Can these screws be used for exterior projects?
Yes, the screws feature rust protection up to 20 times longer than standard zinc plating, making them suitable for exterior applications where corrosion resistance is important.
Are these screws suitable for hardwood?
These screws are designed for demanding timber-to-timber applications and generally perform well in hardwood. Pre-drilling pilot holes is recommended in very dense hardwoods to prevent splitting and ease insertion.
What is the box quantity?
Each box contains 50 TIMco TX40 C2 Clamp-Fix Multi-Purpose Screws.
What are the dimensions of these screws?
The dimensions are 8.0mm in diameter and 225mm in length.
Troubleshooting
Screw cam-out during driving
Ensure you are using a correct, undamaged TX40 drive bit and that it is fully seated in the screw recess. Apply consistent, firm pressure during driving.
Timber splitting
While designed to minimize splitting, pre-drilling a pilot hole, especially near the end of the timber, can further prevent splitting in very dense or brittle wood types.
Excessive insertion torque
Verify the screw is entering the timber straight. Ensure the timber is not excessively dense or wet, which could increase resistance beyond the lubricant's capability.
Screw not achieving full holding strength
Check that the screw has been driven to the appropriate depth and that both timber members are securely engaged by the threads. Ensure the screw is suitable for the load requirements.
Pros and Cons
Pros
Significantly reduces timber splitting with twin-cut technology.
Exceptional holding strength due to dual-angle threading.
Up to 52% reduction in insertion torque for easier driving.
Superior rust protection compared to standard zinc plating.
Prevents cam-out for a secure and controlled installation.
Ensures flush finishes with effective countersinking ribs.
Cons
Requires specific TX40 drive bits, not universally compatible with all screwdriver heads.
The yellow colour may not be aesthetically suitable for all visible applications.
Designed primarily for timber-to-timber applications; performance in other materials may vary.
Setup, Compatibility & Care Instructions
Setup:
Ensure you are using the correct TX40 drive bit compatible with your drill or screwdriver.
Align the screw with the timber members to be joined.
Drive the screw steadily, allowing the lubricant coating and dual-angle thread to engage.
Compatibility:
Drive: Requires a TX40 Torx drive bit.
Material: Primarily designed for use in timber-to-timber applications. Performance in other materials may not be optimal.
Tools: Compatible with most standard power drills and impact drivers equipped with the correct bit.
Care:
Store screws in a dry environment to maintain the integrity of the lubricant coating and rust protection.
Clean any debris from screw heads after installation if necessary, though the TX drive is designed to minimize cam-out.
