Key features

1. Integrated Cutting Ribs. The cutting ribs help enlarge and clear the passage through the upper wood component, reducing shank friction during installation.

2. Secure Torx Drive. The Torx recess provides stable bit engagement and efficient torque transfer while helping reduce slipping and recess damage.

3. Strong Clamping Action. The partially threaded shank helps pull two wooden components tightly together, creating a secure wood-to-wood connection.

4. Neat Countersunk Finish. The raised countersunk head seats neatly into the wood surface and provides a clean finished appearance.

5. Fast Wood Penetration. The sharp point and coarse thread support quick starting and firm engagement in timber and wood-based materials.

SummaryEastland Building Materials Co., Ltd. is a China-based supplier in Nanjing, Jiangsu, associated with manufacturing activities and operating as a trading company while also being identified as a manufacturer/factory.

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 cutting ribs?

A: The cutting ribs help enlarge the passage through the upper wood component, remove wood fibres and reduce friction around the unthreaded shank during installation.

Q:Q2: Why does this screw use a partially threaded design?

A: The partially threaded design allows the threaded section to engage the lower component while the smooth shank passes through the upper component, helping pull the two pieces tightly together.

Q:Q3: What applications is this screw suitable for?

A: It is suitable for wood-to-wood connections, timber structures, furniture assembly, wooden frames and other general woodworking applications.

Q:Q4: Is pre-drilling required?

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

Q:Q5: Is this a self-drilling screw?

A: No. It is a sharp-point self-tapping wood screw with cutting ribs, not a drill-point screw. It should not be described as a TEK or self-drilling screw.
