Q6: Is pre-drilling required?

A: Pre-drilling may not be required for many softwood applications. A pilot hole is recommended for dense hardwood, thick timber or installation close to the wood edge.

Key features

1. Integrated Reaming Ribs. The reaming ribs help enlarge the passage through the upper timber component, reducing friction around the smooth shank during installation.

2. Four-Sided Cutting Point. The multi-edged cutting point supports quick positioning and penetration while helping reduce driving resistance and wood splitting.

3. Secure Torx Drive. The Torx recess provides stable driver-bit engagement and efficient torque transfer while helping reduce slipping during installation.

4. Reliable Clamping Action. The partially threaded design allows the smooth shank to pass through the upper component, helping pull two timber components tightly together.

5. Flush Countersunk Finish. The countersunk head seats neatly into the timber surface, creating a secure connection and a clean finished appearance.

No direct evidence establishes...

Supplier typeThe supplier is classified as a trading company in its company-nature data, while its business-entity classification also includes Trading Company and Manufacturer/Factory. Its stated activities involve developing and manufacturing AAC products, and associated companies are in manufacturing, indicating a mixed trading-and-manufacturing profile rather than a purely trading operation.

CertificationsThe supplier lists ISO 9000, ISO 9001, ISO 14001, ISO 14000, and ISO 20000 management-system certifications. This is explicit evidence of certification holdings, although the slices do not provide certificate numbers, validity dates, or scope details.

Production capacityThe supplier reports fully automatic German production lines and machines, annual production capacity exceeding 1.6 million cubic meters, and manufacturing of AAC panels and blocks. It also reports lead times within 15 working days in both off-peak and peak seasons, providing explicit evidence of substantial stated production capability, although quality-control staffing data is unavailable.

Client casesThe supplier states that its AAC panels have been used in hotels, schools, villas, apartments, shopping malls, and other buildings. The trade record also identifies one associated buyer and one transaction, but it does not provide independently verifiable project names, quantities, locations, or references.

Product Q&A

Q:Q1: What is the function of the reaming ribs?

A: The reaming ribs help enlarge and clear the passage through the upper timber component, reducing friction around the unthreaded shank and supporting smoother installation.

Q:Q2: What is special about the screw point?

A: The screw uses a four-sided cutting point instead of a conventional round conical point. Its cutting edges help the screw start quickly and penetrate wood efficiently.

Q:Q3: Is this a self-drilling screw?

A: No. It is a self-tapping structural wood screw, not a drill-point screw. The four-sided cutting point is designed for wood and should not be described as a TEK screw.

Q:Q4: What is the purpose of the partial-thread design?

A: The threaded section engages the lower timber component while the smooth shank passes through the upper component, helping pull the two parts tightly together.

Q:Q5: What applications is this screw suitable for?

A: It is suitable for timber framing, wood-to-wood connections, wooden beams, structural timber components and other heavy woodworking applications.
