Value Collection JY8962623 Spiral Point Tap 5/16-24 Unf

Product Description

The VALUE COLLECTION JY8962623 is a spiral point plug tap designed for threading 5/16-24 UNF right-hand threads in through-hole applications. Made from high speed steel with a bright uncoated finish, this tap features two flutes and a plug chamfer that helps push chips ahead of the cut rather than packing them into the flute gullets. The H11 thread limit indicates a slightly oversized tolerance of 0.0050 inches, making it well suited for tapping threads that will accept plated or coated fasteners. Licensed machinists, pipefitters, and trade technicians commonly use spiral point taps for production threading in steel, aluminum, and similar materials.

This tap is intended for use in through-hole threading operations where chip evacuation forward through the hole is practical. The 5/16-24 UNF thread form is common in precision mechanical assemblies, HVAC equipment mounting hardware, and general trade fastener applications. The plug chamfer provides a gradual thread lead-in, making it suitable for both hand tapping and machine tapping in a drill press or CNC setup. The oversize H11 tolerance accommodates finish allowances on threaded holes destined for coated or plated fastener engagement.

Key Features

• 5/16-24 UNF right-hand thread form for precision unified fine-thread applications
• Two-flute spiral point design pushes chips forward through the hole during cutting
• Plug chamfer provides gradual thread engagement suitable for machine or hand tapping
• High speed steel construction offers durability across a range of workpiece materials
• H11 thread limit with 0.0050 inch oversize accommodates plated or coated fastener fitment
• Bright uncoated finish — no additional coating variables affecting thread tolerance

Compatibility

Designed as a standard replacement or stocking tap for 5/16-24 UNF through-hole threading operations in trade and production environments.

Installation Notes

This tap should be installed in a tap wrench, drill press, or machine tapping head appropriate for the workpiece setup. Always secure the workpiece before tapping and apply cutting fluid suited to the workpiece material to extend tap life and improve thread quality. Ensure the tap is aligned perpendicular to the workpiece surface before applying cutting pressure. Reverse the tap periodically during hand tapping to break and clear chips from the cutting zone.
