Goliath BSW Intermediate Machine Nut HSS Tap Long Reach

• HSS Bright Finish BSW Machine Nut Intermediate Tap.
• Machine Nut Taps are used where a long shank is needed and are available in Taper, Intermediate, and Bottoming leads.
• To ensure easy and precise use the Machine Nut Tap Taper lead has a unique, very long entering chamfer.
• This makes aligning the cutting end with the work piece simple.
• 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.
• 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.
• We recommend the Intermediate lead Machine Nut Tap for long reach through-hole applications and the Bottoming lead for long reach blind hole applications.
• British Standard Whitworth angle of thread is 55 degrees as opposed to 60 degrees in Metric and Unified threads.
• This thread form was developed by Sir Joseph Whitworth in 1841.
• The thread form has rounded roots and crests and is specified in BS84:1956.
