screwandstrip

Screwandstrip is a term used to describe a two-part fastening system designed to secure panels or hardware by combining a mounting strip with a screw. The mounting strip is attached to a substrate, and the screw engages the strip to clamp the joint. The arrangement spreads clamping force over a larger area and can improve alignment and ease of disassembly in modular assemblies.

Design and operation: The mounting strip is fixed along its length using screws or rivets. The screw either threads into a threaded hole in the strip or engages a captive nut embedded in the strip. As the screw is tightened, it draws the panel toward the strip and produces a secure joint, with load distribution across the strip reducing target point pull-out in softer materials.

Materials and variants: Strips may be metal (such as steel or aluminum) or plastic composites. Screws can be wood screws, sheet-metal screws, or machine screws, depending on the application. Some variants include locking features to resist vibration, such as a captive washer or a clip that prevents loosening.

Applications: Screwandstrip is used in knock-down furniture, cabinetry, panel mounting, electrical equipment housings, and modular installations where repeated assembly and disassembly are advantageous.

Considerations: The system requires precise alignment and predrilled strips and can be more expensive than simple screws for small projects. Its performance depends on the strip material and the screw-strips interface, and it may be less effective in high-vibration or high-load conditions without locking features.
