Four Essential Types of Imperial Workshop Fasteners
High-Tensile Fully Threaded Set Screws – 1,275 Pieces
UNF hexagon head set screws supplied in 13 selected imperial diameter and length combinations for compatible mechanical fastening applications.
Standard UNF Hex Nuts – 1,150 Pieces
Zinc-plated steel standard hexagon nuts supplied in eight imperial fine-thread sizes for use with compatible UNF fasteners.
UNF Nylon Insert Locking Nuts – 475 Pieces
Zinc-plated nylon insert locking nuts supplied in six sizes, designed to provide prevailing torque resistance against loosening in suitable assemblies.
Imperial Heavy-Gauge Flat Washers – 3,200 Pieces
Zinc-plated Table 3 heavy-gauge flat washers supplied in eight dimensions for distributing clamping loads across suitable fastening surfaces.
Important: Verify the required fastener specifications and application suitability before installation.
UNF Fine Thread Fasteners for Engineering & Restoration
UNF stands for Unified National Fine, an imperial thread standard commonly encountered in engineering, machinery and specialist mechanical applications.
UNF threads feature a finer pitch than UNC threads of the same nominal diameter.
These fasteners are particularly useful when maintaining equipment or restoring vehicles where the original assembly specifies UNF fine threads.
The assortment provides a broad selection of compatible UNF nuts and fully threaded set screws for suitable workshop applications.
Important: UNF, UNC and metric threads are not interchangeable. Always verify the correct thread system before installation.
Designed for Existing Workshop Storage Systems
This hardware-only refill kit is intended for customers who already have suitable workshop storage equipment.
It provides 6,100 individual fasteners without additional storage bins, backing panels or organisers.
The assortment can be used to replenish existing parts cabinets, drawer units, wall-mounted storage bins and other suitable fastener storage systems.
By keeping commonly used UNF fixings organised and readily available, workshops can reduce time spent sourcing individual fasteners during maintenance and repair work.
- Hardware Only – 6,100 individual fasteners.
- No Storage Bins – Existing storage equipment required.
- No Backing Panel – Wall-mounted panels are not supplied.
- Flexible Organisation – Suitable for compatible workshop bins, drawers and parts cabinets.
Workshop Fastener Organisation & Replenishment
For efficient stock management, organise the supplied fasteners by type, thread diameter and length.
- Check Existing Stock: Identify the imperial fastener sizes requiring replenishment.
- Prepare Storage Containers: Ensure existing workshop bins or drawers are suitable for the fasteners.
- Separate Fastener Types: Keep standard nuts, nylon locking nuts, washers and set screws organised independently.
- Organise by Diameter: Group UNF fasteners according to their imperial thread size.
- Separate Set Screw Lengths: Arrange fully threaded set screws by diameter and length.
- Label Storage Locations: Clearly identify the UNF thread sizes to prevent confusion with UNC or metric components.
- Maintain Stock Levels: Replenish frequently used sizes as required.
Important: Do not mix different thread systems, strength grades or fastener specifications in the same storage compartment.
Zinc-Plated UNF Nuts & Heavy-Gauge Washers
The supplied standard hex nuts, nylon insert locking nuts and heavy-gauge flat washers are identified by the supplier as zinc plated.
Zinc plating provides a protective surface finish that helps resist corrosion under suitable environmental conditions.
This makes the components useful for appropriate general workshop, engineering and mechanical maintenance applications.
Important: The exact set screw finish and strength classification should be confirmed separately. Zinc plating does not automatically make fasteners suitable for marine, structural or safety-critical applications.
Safety, Compatibility & Important Information
- Thread Identification – Confirm the correct UNF diameter and thread pitch before installation.
- Fastener Strength – Verify the required strength grade for the intended application.
- Correct Tightening – Follow applicable torque and assembly specifications.
- Nylon Locking Nuts – Observe appropriate installation and reuse requirements.
- Washer Selection – Confirm washer dimensions and load requirements.
- Material Compatibility – Verify suitability for the operating environment.
- Safe Storage – Keep fasteners clean, dry and correctly identified.
- Safety-Critical Applications – Do not use without confirming the required specifications and approvals.
Important: This refill assortment is intended for suitable general workshop, engineering and maintenance applications. No specific structural approval, strength classification or durability guarantee is implied unless separately confirmed.
