Unifix BZP CSK Twinthread Woodscrews 4 x 1/2 BOX BOX 200 OJ077857

This box contains 200 countersunk twinthread woodscrews, each measuring 4 x 1/2 inch, with a bright zinc-plated (BZP) finish. Designed for securing timber and wood-based materials, these screws are suitable for a range of internal joinery and general construction work where a flush finish is needed.

The twinthread design allows for quicker insertion and improved grip in softwoods and chipboard. A practical choice for carpenters and general trades, these woodscrews are commonly used for fixings such as securing panels, battens, and other wood assemblies on site.
