What installation tool should be used?

A matching hex socket or nut setter with a speed-controlled power tool should be used. The recommended speed and torque depend on the screw diameter, drill point and metal thickness.

Can the specifications and packaging be customized?

Yes. The diameter, length, thread specification, drill-point size, material, surface finish, labels and packaging can be customized according to customer requirements.

Key features

1. Integrated Drill Point. The drill point combines drilling and thread-forming operations, helping reduce installation steps within the specified metal thickness range.

2. External Hex Drive. The external hex head is compatible with socket drivers and provides stable tool engagement for efficient installation.

3. Wide Flange Bearing Surface. The integrated flange distributes fastening pressure over a larger contact area, helping support a stable metal connection.

4. Continuous Thread Engagement. The fully threaded shank provides continuous engagement after the drill point penetrates the connected metal components.

5. Customizable Drilling Performance. Different diameters, lengths, drill-point sizes, materials and surface finishes can be customized for specific metal thicknesses and applications.

AI-Powered supplier vetting

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. Its stated business focuses on AAC/ALC panels, blocks, floor slabs, and related construction products. The supplier reports German-origin automated production equipment and annual capacity exceeding 1.6 million cubic meters, indicating substantial stated production capability. It lists multiple management-system certifications and serves several international regions. Exporting reportedly began in 2014, with quotations available under CFR, FOB, and CIF terms and payment accepted by LC or T/T. However, quality-control staffing, R&D engineer experience, and overall staff experience are unavailable. The available trade record shows one transaction and one associated buyer, while customer-use descriptions cover hotels, schools, villas, apartments, and shopping malls. 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:What is the difference between a self-drilling screw and a self-tapping screw?

A self-drilling screw has an integrated drill point that can drill and form threads in one operation. A conventional self-tapping screw normally requires a pre-drilled or punched pilot hole.

Q:Does this screw require pre-drilling?

Pre-drilling is generally not required when the material type and total thickness are within the rated drilling capacity of the screw point.

Q:What materials can this screw be used with?

It is designed for sheet metal, light-gauge steel and related metal assemblies. The appropriate drill point must be selected according to the material hardness and total thickness.

Q:What is the purpose of the flange head?

The integrated flange provides a wider bearing surface than a standard hex head, helping distribute fastening pressure across the connected component.

Q:Is a separate washer required?

A separate washer may not be necessary for many general metal fastening applications because of the integrated flange. For waterproofing or sealing applications, a suitable bonded EPDM washer may still be required.
