Secure fittings – with captive washer

Captive washer stays fixed to the screw body during handling and insertion, preventing the washer from falling away. The integrated design streamlines alignment, especially in awkward or single-handed installations.

Faster, neater fittings with fewer lost washers and reduced need for a second pair of hands during installation.

Improved corrosion resistance – with zinc-plated finish

A zinc-plated surface layer is applied to the screw and washer, creating a barrier that resists surface oxidation under normal indoor conditions. The finish is consistent across the supplied batch.

Suitable for routine indoor and sheltered applications where basic rust protection and consistent appearance matter.

Neat storage and handling – with resealable bag

Packaged in a resealable bag that keeps components together between jobs, allowing quick access and reduced spillage on site. The bag helps maintain organisation in a busy toolbox or workshop.

Less time spent sorting screws, fewer losses, and easier transport between work locations.
