Description
Overview:
The 3 BA Open Ended Single Sided Spanner is a compact hand tool for working on older British equipment that uses BA fasteners. Made from durable steel for long service life, it provides a firm grip on BA hex nuts and bolts where accurate sizing matters. Its single open end and slim profile make it practical in tight areas such as control panels, small engines, garden machinery, and precision assemblies found on vintage kit. Supplied as new old stock, it retains original quality and strength, though minor tarnishing or marks from storage may be present. This is a useful choice for repairs, restoration, and maintenance on legacy machinery, instruments, and fixtures that still rely on British Association thread standards and matching hex sizes.
Key Features:
- 3 BA sizing for a correct fit on BA nuts and bolts used on vintage and legacy equipment
- Single-ended, open-jaw design for quick placement and removal in tight or obstructed spaces
- Steel construction for durability and consistent torque transfer
- Slim, lightweight form factor for delicate assemblies and reduced risk of rounding fasteners
- New old stock (NOS): unused original item with possible light storage tarnish or minor cosmetic wear
- Suitable for workshop, site toolkits, and field service where BA fixings are encountered
- Smooth jaw faces to help protect fastener corners on older or softer materials
- Handy for maintaining classic machinery, instruments, and heritage garden or construction tools
Typical Applications:
Used for assembly and maintenance on vintage machinery, electrical panels, instruments, model engineering projects, classic garden and construction tools, and other equipment built with BA fixings. Ideal for fine adjustments, periodic servicing, and restoration work where exact BA sizing prevents damage to fasteners and ensures reliable reassembly.
