Upholstery Screw for Chairs Rystor RYSTOR PIS.KRES.1,40 — metal fixing element, MPN RYST0180

Rystor PIS.KRES.1,40 is a metal upholstery screw designed for chair construction and furniture fastening. This single-item metal fixing element is intended to join wooden or metal frame parts, fasten seat and back components, and secure upholstery fittings where a compact threaded fastener is required. The screw’s metal construction provides stability and resistance to deformation in typical furniture assembly and repair tasks.

Advantages

The metal design offers strength and dimensional stability under load, making it suitable for repeated assembly and disassembly during repair or adjustment. Its compact size allows installation in confined or recessed areas of chair frames without compromising the surrounding material. The screw’s thread and head geometry are optimized for secure retention of upholstery components and for reliable mechanical connection between parts.

Suitable for

• Chair frame assembly and repair
• Securing seats, backs and arm supports
• Attaching upholstery fittings and decorative elements
• Replacement of worn or missing chair fasteners

Key specifications

• Material: metal (durable steel alloy)
• Intended use: upholstery and furniture fastening
• Design: single-item compact screw for confined fittings
• Function: mechanical joining of frame parts and attachment of upholstery components

How to use

Select a compatible pilot hole or pre-drill according to the receiving material to avoid splitting or deformation. Insert the screw into the mating component and tighten with an appropriate screwdriver or driver bit until the assembly is secure; avoid over-torquing to prevent thread stripping or material damage. For best results, align components precisely before final tightening and check that upholstery and frame elements are correctly seated.

Usage recommendations

Use corrosion-resistant washers or protective coatings in humid environments and periodically inspect fastened joints for loosening. When replacing existing fasteners, match the screw’s dimensions and thread form to the original to maintain structural integrity.
