Description
Overview:
Acme Screws with Captive Washers, Assorted Box (120 pieces) are zinc‐plated steel fasteners designed for quick, secure assembly across construction, workshop and garden machinery tasks. The hexagon head offers positive drive with a spanner, socket or nut driver, while the captive washer is pre‐assembled to the screw to spread load and help resist loosening under vibration. The mixed selection covers popular gauges and short lengths for panel, bracket and enclosure fixings where space is limited. Typical lengths included are 1/2 in (13 mm) and 3/4 in (19 mm) across common gauges No. 8, No. 10, No. 12 and No. 14, giving enough range for day‐to‐day maintenance and light fabrication. Supplied in a practical 120‐piece box for general repairs on site equipment, power tools, and garden machines such as mowers or generators.
Key Features:
- Zinc‐plated steel for improved corrosion resistance and a clean, durable finish suitable for indoor and outdoor use
- Hexagon head for strong drive engagement with spanner or socket; reduces cam‐out compared with cross‐head screws
- Captive washer pre‐fitted to each screw for faster assembly, better load spread, and improved resistance to vibration loosening
- Assorted common sizes: a mix of No. 8, No. 10, No. 12 and No. 14 in 1/2 in (13 mm) and 3/4 in (19 mm) lengths
- 120‐piece box provides a handy selection for routine repairs, installations and spares kits
- Suitable for fastening into pre‐drilled metal, plastics and timber where a washered hex screw is preferred
- Smooth, consistent threads for reliable grip and repeatable tightening torque
- Bright silver finish is easy to identify in toolboxes and low‐light work areas
Typical Applications:
General fixing of panels, guards, brackets and hinges on construction equipment and garden machinery. Useful for assembling jigs, frames, racking, control boxes and light enclosures. Ideal for maintenance on mowers, generators, pressure washers, compactors and site accessories where a short hex screw with an integral washer gives a tidy, secure hold.
