Product Description
3/8" BSF self colour hexagon head bolts manufactured from Grade R high tensile steel, equivalent to 8.8 grade. These imperial British Standard Fine bolts have an unthreaded shank and are suitable for engineering, machinery, automotive, restoration, fabrication and general repair applications.
The hexagon head allows installation with a standard spanner or socket, while the BSF thread provides the traditional British Standard Fine thread form used on many classic vehicles, older machinery and imperial engineering assemblies.
These 3/8" BSF bolts have a 20 TPI thread and are supplied in a self colour / plain steel finish. Available in imperial lengths from 1 3/4" to 3 1/2", with pack sizes suitable for single repairs, workshop use and bulk stock.
