Goliath UNC Straight Flute Tap - Taper HSS Bright

• HSS Bright Finish UNC Hand and Machine Taper Tap.
• HSS Straight Flute Short Machine and Hand Taps.
• These general-purpose taps are ideal for creating new threads in a wide variety of materials.
• Goliath HSS taps provide a high hardness-to-toughness ratio, compressive and tensile strength, good abrasion resistance and resistance to micro-chipping, ensuring a long tool life.
• The Unified National Coarse thread form was introduced in 1948 as an attempt to standardise thread forms in the USA, Canada, and the UK.
• The thread profile of UNC is the same as for metric threads and is described in the JIS B0206 standard.
• The thread is described by its major diameter and the number of threads per inch of length (TPI).
• This thread series is commonly used in the mass production of bolts, screws, and nuts.
• It is used for threading into lower tensile strength materials (bronze, brass, aluminium and plastics) to obtain the best resistance to stripping of the internal thread.
• It is also used on quick assembly or disassembly or if corrosion or slight damage is possible.
• Taper Taps have a lead of eight threads and are used as a starting tap in difficult or high precision holes.
• Manufactured from HSS this general-purpose tap is designed for use in medium tensile materials and is for hand or general machine use.
