Goliath UNC Intermediate Left Hand HSS Tap

• Left Hand HSS Bright Finish UNC Hand and Machine Intermediate 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.
• Intermediate Taps have a lead of four threads and are used in most general-purpose applications to cut a thread true to a pre-drilled pilot hole.
• Manufactured from HSS this general purpose tap is designed for use in medium tensile materials and is for hand or general machine use.
