Value Collection JY4747168 Straight Flute Tap 3/4-16 Unf

Product Description

The VALUE COLLECTION JY4747168 is a straight flute plug tap designed for cutting right-hand internal threads in a 3/4-16 UNF configuration. Machined from high-speed steel with a bright, uncoated finish, this tap is built for threading operations in ferrous and non-ferrous metals where a standard hand or machine tap setup is required. With four flutes and a plug chamfer, it is suited for through-hole threading applications where chip clearance and thread lead-in are priorities. The overall length of 4.25 inches accommodates standard tap holder setups. The H11 thread limit designation indicates a slightly oversize grind, offset by 0.0050 inches, which accounts for material springback in tighter-tolerance threading jobs.

This tap is intended for use in machine shops, maintenance and repair operations, and production threading applications. The plug chamfer style provides a gradual lead-in, making it appropriate for through holes where the tap can pass completely through the workpiece. The 3/4-16 UNF thread form is a fine-pitch unified national fine standard commonly found in precision fastener applications including automotive, hydraulic fittings, and instrumentation assemblies. Licensed machinists, toolroom technicians, and maintenance tradespeople are the primary users of this tool.

Key Features

• Plug chamfer for gradual thread lead-in in through-hole applications
• 4 straight flutes for chip clearance and consistent thread formation
• High-speed steel construction for durability across common workpiece materials
• H11 thread limit with 0.0050 inch oversize grind for springback compensation
• Bright, uncoated finish — no additional coating treatment
• 4.25 inch overall length for compatibility with standard tap holders

Compatibility

Designed as a standard replacement or production tap for any application requiring a 3/4-16 UNF straight flute plug tap in a right-hand thread configuration. Fits standard tap holders and tapping heads sized for 3/4 inch taps.

Installation Notes

This tap is intended for use by qualified machinists or maintenance tradespeople familiar with threading operations. Always secure the workpiece firmly before tapping and ensure the spindle or tap wrench is properly aligned to avoid tap breakage. Use an appropriate cutting fluid for the workpiece material to extend tap life and improve thread finish. Inspect the tap for wear or chipping before each use, as a damaged cutting edge will produce out-of-tolerance threads.
