Concrete Screw

Product Specifications

Technical details and manufacturing context for Concrete Screw

Definition

A concrete screw is a hardened threaded anchor installed into a correctly drilled hole in concrete or masonry. It fastens brackets, channels, frames or fixtures where the exact anchor approval covers the base material and loading. Buyers should specify product approval, base material and condition, diameter, embedment, fixture thickness, edge distance, spacing, installation torque and load data. Safety and load values must come from the selected product standard, approval, drawing or test report; they cannot be inferred from appearance or nominal size. The RFQ should also state quantity, packaging, inspection and traceability requirements.

Working Principle

The hardened thread cuts or forms a load-bearing path in the drilled hole; capacity is product-, substrate- and installation-specific. The screw engages with the concrete or masonry through mechanical interlock, and the load transfer depends on the precise hole diameter, embedment depth, and the quality of the base material. Installation torque affects the seating and preload, but the ultimate performance is defined by the product approval and test data. Edge distance and spacing must be maintained to avoid concrete edge failure or group effects. The screw is not intended for dynamic or seismic loading unless explicitly covered by the approval. Always verify the specific product's load tables and installation instructions.

Frequently Asked Questions

What information must be provided when requesting a quote for concrete screws?

The RFQ should include the product approval, base material and condition, diameter, embedment, fixture thickness, edge distance, spacing, installation torque, and load data. Also specify quantity, packaging, inspection, and traceability requirements.

Can load values be determined from the screw's appearance or nominal size?

No. Load values must come from the selected product standard, approval, drawing, or test report. They cannot be inferred from appearance or nominal size alone.

What materials are available for concrete screws?

Hardened carbon steel is typical, and stainless steel is available where approved. The specific material must be confirmed against the product approval and the exposure conditions.

Why is installation torque important?

Installation torque affects the seating and preload of the screw. The correct torque is specified in the product approval or installation instructions and must be followed to achieve the intended performance.
