Description
Overview:
These UNC steel nuts are general‐purpose fasteners for securing components on construction, agricultural, and garden machinery. Made from robust carbon steel with a bright zinc‐plated finish, they offer dependable strength and resistance to rust in everyday outdoor and workshop conditions. The 1/2" size (12.7 mm) suits matching 1/2" UNC bolts and studs, providing a stable clamp for frames, brackets, guards, and engine or chassis fittings. The classic hexagon form allows quick tightening with standard spanners or sockets. Supplied in a pack of 100, they are a practical choice for site work, maintenance teams, and DIY users who need consistent, ready‐to‐use fixings. Precision‐cut threads help ensure smooth assembly and secure seating under vibration and load.
Key Features:
- Steel construction for reliable tensile strength and long service life
- Zinc plating for corrosion resistance in damp, outdoor, and workshop environments
- 1/2" UNC size (12.7 mm) for compatibility with common coarse‐thread fasteners
- Hexagon profile for easy use with spanners and socket sets
- Clean, precise threads for consistent fit and grip
- Suitable for machinery, fabrication, and structural fixings where a robust clamp is needed
- Bright finish helps visual inspection and identification on site
- Bulk pack of 100 to support larger jobs and routine maintenance
- Consistent dimensions to aid repeatable torque application
- Versatile choice for steelwork, brackets, guards, and equipment mounting points
Typical Applications:
Used for assembling and maintaining construction plant, garden machinery, trailers, steel frames, fixtures, guards, brackets, and engine accessories. Common in mower decks, compressors, generators, compactors, site lighting rigs, and workshop jigs. Suitable for fastening to threaded studs or bolts where a coarse UNC thread is preferred for durability and quicker assembly in general‐purpose fabrication and repairs.
