Key features

1. Secure Hex Socket Drive. The hex socket provides stable tool engagement and efficient torque transfer for controlled installation.

2. Flush Countersunk Finish. The countersunk head sits neatly flush with the wood surface, creating a smooth and clean finished appearance.

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

4. Long Smooth Shank. The extended unthreaded shank is suitable for joining thicker wooden components where controlled positioning and clamping are required.

5. Firm Thread Engagement. The sharp point and coarse thread support quick starting and reliable engagement in timber and common wood-based materials.

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 drive type does this screw use?

A: The product shown in the image uses a hex socket drive. A matching square driver bit should be selected according to the recess size.

Q:Q2: What is the purpose of the partial-thread design?

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

Q:Q3: Does the countersunk head sit flush with the wood surface?

A: Yes. When installed correctly, the countersunk head can sit flush with or slightly below the wood surface, creating a neat finished appearance.

Q:Q4: What applications is this screw suitable for?

A: It is suitable for timber construction, wooden frames, furniture assembly and other wood-to-wood connections requiring a partially threaded shank.

Q:Q5: Is pre-drilling required?

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