Goliath 1/4" x 26 TPI BSF Fluteless (Roll | AIMS Industrial

Applications

• Materials with a minimum elongation of 5% and a tensile strength no greater than 1,000 N/mm2 are suitable for thread forming
• Fine threads are also used where the length of engagement is limited or where wall thickness demands a fine pitch
• Manufactured from HSS this fluteless tap is designed for use in medium tensile materials and is for hand or general machine use

Specifications

• 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
• The thread is formed by the tap in the ductile material creating threads that have a smoother surface and greater tensile strength under dynamic stress than cut threads
• When used on external threads this series has greater tensile stress area than coarse threads of the same size
• HSS-Co (Cobalt) Bright Finish BSF Fluteless Machine Tap
• HSS Fluteless (Roll Form) Taps
• Fluteless taps are also referred to as "Roll Form" or "Thread Flow" taps
• Unlike standard taps, fluteless taps create internal threads by pressure deformation, rather than by material removal
• It is essential to use a high quality lubricating fluid when using fluteless taps
• IMPORTANT - Fluteless Taps use different tapping drill sizes than standard taps
