## Long description

Uni screw pack from Koelner/Rawlplug containing 14 stainless steel screws sized 3 x 40 mm. These corrosion-resistant screws are designed for general fastening tasks where a compact 3 mm diameter and 40 mm length suit assembly, repair and mounting jobs. The stainless steel construction provides durability and resistance to rust, making the screws appropriate for indoor and mildly humid environments when used with compatible anchors or pilot holes.
Advantages
Stainless steel construction ensures long-term corrosion resistance and dimensional stability. The 3 x 40 mm size balances small diameter access with sufficient penetration depth for light to medium fastening applications. Supplied as a set of 14 pieces, the pack offers a ready quantity for small projects, repairs or replacements. The screws are compatible with metal, wood and plastic substrates when correct pilot holes or anchors are used.
Suitable for
Fixing small metal parts and brackets
Securing fixtures to wooden surfaces
Assembly and repair of plastic components
Light mounting tasks in kitchens, bathrooms and workshops
Key specifications
Material: stainless steel (corrosion-resistant)
Diameter: 3 mm
Length: 40 mm
Quantity in pack: 14 pieces
Intended substrates: metal, wood, plastic (use appropriate pilot holes or anchors)
How to use
Determine the appropriate pilot hole diameter and depth for the 3 x 40 mm screw based on the substrate and anchor type. Pre-drill a pilot hole where required, insert a compatible anchor if fastening to masonry or hollow materials, align the parts to be joined and drive the screw until the head is flush with or slightly below the surface as needed. Use a screwdriver or compatible bit and a controlled torque to avoid over-tightening, especially in soft materials.
Usage recommendations
For best results, match the screw with anchors rated for stainless steel fasteners when installing into masonry or hollow-wall systems; in metal and wood applications, select pilot holes sized for the 3 mm diameter and reduce torque on delicate materials to prevent stripping.
