Self-tapping metal screws Koelner/Rawlplug M5 x 50 mm zinc-plated, pack 8 pcs (B-82202-0550-OC)

Set of Koelner/Rawlplug self-tapping metal screws M5 x 50 mm with zinc plating, supplied in a pack of 8 pieces. These self-tapping screws are designed to form or follow a thread in metal and thin sheet materials, providing a reliable mechanical connection where a metric M5 thread and 50 mm length are required. The zinc-plated finish increases resistance to corrosion in normal indoor and covered outdoor environments and ensures consistent performance for construction, metalworking and general repair tasks.

Advantages

Self-tapping design eliminates the need for pre-tapping in many applications, saving time during installation. The M5 nominal thread size and 50 mm shank length offer compatibility with common metal components and assemblies. Zinc plating provides a protective layer against rust and extends service life under typical exposure conditions. Supplied in a small pack of 8 pieces, the set is convenient for small projects, repairs and on-site adjustments.

Suitable for

• Fastening thin metal sheets and light-gauge steel components
• Joining metal brackets, profiles and housings
• Repair and maintenance tasks in workshops and construction sites
• Applications requiring M5 thread engagement with 50 mm length

Key specifications

• Thread size: M5 (metric)
• Length: 50 mm (overall/usable shank length as applicable)
• Finish: Zinc-plated for corrosion resistance
• Type: Self-tapping metal screw (designed to form or follow threads in metal)
• Pack quantity: 8 pieces

How to use

Select an appropriate pilot hole size if required by material thickness and hardness, or drive the screw directly into thin sheet metal where self-tapping is suitable. Use a compatible screwdriver or driver bit that matches the screw head type and apply steady axial pressure while turning to ensure correct thread formation. Ensure mating components are properly aligned and, if necessary, use washers or clamps to distribute load and prevent material deformation. Tighten to a torque appropriate for M5 self-tapping screws in the specific substrate to avoid stripping or over-tightening.

Usage recommendations

For outdoor or high-humidity environments consider additional corrosion protection such as sealing compounds or alternative fasteners with enhanced corrosion resistance. When fastening harder metals or thick sections, pre-drill and tap or select a fastener designed for the substrate to prevent damage. Store the screws in a dry place to preserve the zinc finish.
