20pc BSF BRITISH STANDARD FINE THREAD TAP & DIE SET
Not Boxed - 1/4"-1/2" 55dec angle pitch
BSF threads are generally not used in today's modern industry, but the Old English thread is very common in older English equipment such as Vintage Cars & Motor Bikes ect.
Our taps and dies are made from Quality Carbon Steel which have a well finished Ground Thread. All our ranges of Taps & Dies are new (Unless stated otherwise) & are made by specialist thread manufacturers. Please check out our feed back and comments. We have designed these little package deals of common smaller BSF sizes to save you guys some money as buying individual sizes certainly adds up. These are the perfect kit for small BSF threads.
Each Tap set comes with a Plug, Intermediate & Taper Tap in each size (1/4", 5/16", 3/8", 7/16" & 1/2"). Giving you a total of 15 Taps all up.
You also get a matching Button die to suit each size. The 1/4", 5/16" & 3/8" dies will be 1"OD whilst the 7/16" & 1/2" will be 1.1/2" OD.
