Value Collection JY4992509 M8x1.00 Plug Hand Tap Hss

Product Description

The VALUE COLLECTION JY4992509 is a metric fine hand tap designed for cutting right-hand internal threads in through holes and moderately deep blind holes. Built from high speed steel with a bright uncoated finish, this 4-flute straight flute tap handles M8 x 1.00 thread profiles. The plug chamfer — typically 3 to 5 threads — makes it well suited for starting in a pre-drilled hole and following through to full thread depth. Overall length is 2.719 inches and thread length is 1.125 inches, keeping the tool compact for bench work and handheld tapping operations. Machinists, tool and die technicians, and maintenance mechanics reach for this style of tap regularly.

This tap is used wherever M8 x 1.00 metric fine internal threads are required — common in automotive components, precision machinery, hydraulic fittings, and general fabrication. The metric fine pitch of 1.00 mm provides tighter thread engagement than the coarse M8 x 1.25 standard, which is advantageous in applications requiring vibration resistance or finer adjustment. It is suited for hand tapping operations using a standard tap handle or T-handle wrench in a bench or field maintenance setting.

Key Features

• M8 x 1.00 metric fine thread profile for tight-pitch internal thread cutting
• Plug chamfer (D3 thread limit) for versatile starting in pre-drilled holes
• 4-flute straight flute design for efficient chip clearance in through-hole and moderate blind-hole applications
• High speed steel construction provides durability across a range of workpiece materials
• Bright uncoated finish — no added coating to affect dimensional tolerance
• Right-hand thread direction, standard for the vast majority of fastening applications

Compatibility

Designed as a standard hand tap for use with conventional tap handles and T-handle wrenches sized for the square drive shank of an M8-class tap. Suitable for use in steel, aluminum, brass, and similar machinable materials.

Installation Notes

Secure the workpiece firmly before tapping. Use cutting fluid appropriate to the workpiece material to reduce heat and extend tap life. Apply steady, even pressure and back off periodically to break chips, especially in blind holes. Avoid forcing the tap if resistance increases sharply, as high speed steel taps are brittle under torsional overload.
