Chipboard Screw

A chipboard screw is a wood-based-panel fastener with a sharp point, deep thread and usually a countersunk head. It is used in furniture, cabinetry, joinery and general timber or panel assembly. The sharp point starts in the panel and the deep thread develops holding force in the wood fibres while the head seats flush. Buyers should specify board material, diameter, length, partial or full thread, head, drive, point and coating. Standards listed here govern particular forms and do not make sizes, materials or finishes interchangeable. The RFQ should state the exact standard or drawing, required configuration, quantity and inspection evidence. Materials on file include hardened carbon steel and stainless steel by application. Parameters such as applicable standard, nominal size, material, strength/performance, surface finish and RFQ selection fields are listed as catalog references under DIN 7505. These values must be confirmed against the selected standard, drawing and supplier evidence. The DIN 7505 reference is a procurement and verification aid, not a certification of compliance. Always verify model-specific values and standards with the legal manufacturer or supplier before ordering. This directory entry is for reference only and does not imply that any product is certified or compliant. For correct selection, consider the board type, screw dimensions, thread coverage, head style, drive type, point geometry and coating. Performance depends on the interaction of these factors with the specific board material. Inspection evidence may include dimensional checks, material certificates or test reports as agreed in the RFQ. The working principle relies on the screw displacing wood fibres rather than cutting them, which can affect holding strength and the risk of splitting. In dense boards, pilot holes may be necessary. The screw is typically driven with a power tool at controlled torque to avoid over-tightening and stripping. The head seating flush is important for a neat finish and to avoid protrusion. The deep thread provides resistance to pull-out, while the sharp point aids penetration. The choice of coating affects corrosion resistance and friction during driving. Stainless steel is selected for damp or outdoor applications. The catalog reference DIN 7505 covers certain forms, but the actual product must be specified by the buyer. Always confirm the exact standard or drawing with the supplier.
