Stainless steel screw Koelner/Rawlplug 3.5x25 mm, pack of 20 pieces, is a corrosion-resistant fastening solution for general assembly, woodworking and light metalwork where a 3.5 mm diameter and 25 mm length are required. Supplied in a retail blister, this stainless steel screw is intended for applications that need durable, weather-resistant fasteners for both indoor and outdoor use.

Advantages

Made from stainless steel, the screw offers enhanced resistance to rust and corrosion compared with standard steel fasteners. Its 3.5 mm diameter and 25 mm length provide a balance between holding strength and minimal material disruption in thin panels, wood and light metal joints.

How to use

Select an appropriate pilot hole size for the 3.5 mm screw based on the material being fastened; for hardwoods and metals a pilot hole is recommended to prevent splitting or deformation. Place the screw through the components to be joined and drive it using a matching screwdriver or a compatible bit with controlled torque to avoid over-tightening. For repeated outdoor exposure, ensure mating materials and any accessories are also corrosion-resistant to maintain overall joint durability.

Usage recommendations

Store the blister pack in a dry place to preserve the stainless surface and prevent contamination. When fastening into thin or brittle materials, use a washer if needed to distribute load and reduce the risk of pull-through. For critical structural applications, verify that the screw dimensions and material grade meet required load and safety specifications.
