This hand tap with 1/4-20 threads per inch United National Coarse (UNC) designation provides precision threads for metal or plastic fastening projects while eliminating the need for an air or electric powered tapping machine, making it convenient and cost-effective to use. The H2 chemical composition ensures high-speed steel resilience against standard machining conditions with the inclusion of three flutes that provide better chip evacuation from the cut minimizing friction heat build up for extended tool life while creating smooth, clean threads preventing assembly damage. Its plug chamfer design reduces the risk of thread galling or overstress in delicate components promoting consistent, high-quality thread starts across various materials ranging from soft metals to aluminum, bronze, brass or stainless steel perfect for small-scale hobbyists and maintenance technicians seeking an all-purpose tapping solution at a budget-friendly price.
