Goliath 3/4" x 12 TPI BSF Bottom Machine Nut HSS Tap - L18BK3

Applications

• Machine Nut Taps are used where a long shank is needed and are available in Taper, Intermediate, and Bottoming leads
• Ideal for tapping nuts, small quantities made from tough steel such as stainless steel as well as mild steels, or for rethreading rusty or worn threads
• Fine threads are also used where the length of engagement is limited or where wall thickness demands a fine pitch

Specifications

• Alternatively, the Intermediate and Bottoming leads are ideally suited to long reach threading applications where the thread needing to be tapped or cleaned is beyond the reach of a standard tap
• British Standard Fine thread form was based upon the British Standard Whitworth (BSW) but has a finer thread (more threads per inch for a given diameter)
• The thread form was first introduced in 1908 and is specified in BS84:1956
• When used on external threads this series has greater tensile stress area than coarse threads of the same size
• HSS Bright Finish BSF Machine Nut Bottoming Tap
• To ensure easy and precise use the Machine Nut Tap Taper lead has a unique, very long entering chamfer
