Straight Flute Tap: #3-56 UNF, 3 Flutes, Plug, 2B Class of Fit, High Speed Steel, Bright/Uncoated MPN:300645

The #3-56 UNF straight flute tap with a plug style provides excellent thread quality in materials such as aluminum or brass suitable for applications that require precision including the aerospace, medical & electronics industries requiring clean, uniform threads. The high speed steel construction delivers enhanced strength, wear resistance in longer run times while 3 flutes minimize chip buildup providing efficient chip removal. A 2B class of fit guarantees proper thread form as required on UNC or UNF thread types reducing assembly errors ensuring smooth performance by manufacturers utilizing uncoated tap for better lubricity resulting in smoother, cleaner threads reducing stress fractures when mating fasteners are applied.
