Plug tap with open or through hole threads - Key function: Creates internal threads in holes, enabling secure fastener assembly in open or through holes. - Material: HSS-E substrate provides high hardness and wear resistance for durability in metalworking applications. - Finish and reliability: Steam-oxide finish helps prevent welding or galling between the tap and workpiece, improving thread formation and tool life. - Performance benefits: Durable for repeated use, maintains accurate thread profiles, and delivers consistent results across common metal tapping tasks. - Compatibility notes: Designed for use with standard hole sizes and threading operations that require a plug tap with open or through hole capability. - Practical use scenarios: 1) Tapping through holes in a steel bracket to mount a hinge or hardware with reliable threaded fasteners. 2) Creating threaded mounting holes in aluminum panels for electronic enclosures or control boxes. 3) Repairing or rethreading damaged internal threads in machinery housings to restore proper fit for fasteners. - Key attributes at a glance: plug tap, open or through hole threading, HSS-E substrate, steam-oxide finish, improved tool life and reduced risk of welding.
