Value Collection JY4990453 M1.6x0.35 Hand Tap Plug Rh

Product Description

The VALUE COLLECTION JY4990453 is a straight-flute hand tap designed for cutting M1.6 x 0.35 metric coarse internal threads by hand. Made from high speed steel with a bright uncoated finish, this tap delivers consistent thread form in small-diameter through-holes and blind holes. The plug chamfer configuration provides a balance between starting ease and thread engagement, making it suitable for general-purpose tapping operations. With an overall length of 1.625 inches and a thread length of 0.3125 inches, this is a compact tool intended for precision work in tight or confined applications. Licensed machinists, tool-and-die makers, and maintenance technicians are the typical users.

This tap is suited for light-duty manual tapping in small fastener applications where metric coarse threads are required. The M1.6 x 0.35 thread size is common in electronics enclosures, instrument housings, small mechanical assemblies, and precision fixtures. The 2-flute straight flute geometry works well in through-hole applications and accommodates chip evacuation during hand tapping. The D1 thread limit designates a tight tolerance class appropriate for standard fit thread forms in production and repair work.

Key Features

• M1.6 x 0.35 metric coarse thread form for small-diameter internal threads
• High speed steel construction provides wear resistance for manual tapping operations
• Plug chamfer for reliable thread starting and consistent engagement
• D1 thread limit for standard fit tolerances
• 2-flute straight flute design aids chip clearance in through-hole applications
• Bright uncoated finish suitable for use with standard cutting fluids

Compatibility

Designed as an OEM-style hand tap for general metric coarse tapping applications requiring an M1.6 x 0.35 thread size with a D1 thread limit and plug chamfer configuration.

Installation Notes

This tap is intended for hand tapping only and should be used with a properly sized tap wrench. Apply a suitable cutting fluid for the workpiece material to extend tool life and improve thread quality. Ensure the tap is aligned perpendicular to the workpiece before beginning to avoid thread distortion or tap breakage, which is a significant risk at this small diameter. Inspect the tap for wear or chipping before each use, as high speed steel tooling at this size class is susceptible to breakage under side load or misalignment.
