Value Collection JY4840930 Hand Tap 9/32-40 Uns Hss

Product Description

The VALUE COLLECTION JY4840930 is a straight-flute hand tap designed for cutting 9/32-40 UNS internal threads in a shop or field environment. Built from high speed steel with a bright uncoated finish, this plug-chamfer tap is suited for through-hole and moderate-depth blind-hole tapping by hand. The 4-flute geometry provides balanced cutting action and good chip clearance for most common materials. With a thread limit of H2 and a Class 3B fit tolerance, it produces close-tolerance threads consistent with standard UNS specifications. Overall length is 2-23/32 inches, making it compatible with standard tap wrenches and T-handles used in maintenance and production tapping work.

This tap is intended for right-hand threading operations on the 9/32-40 UNS thread form, a fine-pitch size used in precision mechanical assemblies, instrument hardware, and specialty fastener applications. It is suited for use in metals and other machinable materials where a hand-tapping approach is appropriate. Machinists, tool and die makers, and maintenance technicians performing manual threading operations are the primary users of this tap type.

Key Features

• Thread size 9/32-40 UNS with right-hand direction for standard internal thread cutting
• Plug chamfer (3-5 thread lead) allows starting in through holes or blind holes with adequate clearance
• High speed steel construction provides hardness and wear resistance for hand tapping applications
• Bright uncoated finish suitable for general-purpose use across a range of workpiece materials
• 4-flute straight-flute design promotes balanced cutting load and chip management
• H2 thread limit and Class 3B fit tolerance for close-tolerance thread production

Compatibility

Designed for hand tapping 9/32-40 UNS threaded holes; compatible with standard tap wrenches and T-handle drivers sized for this tap shank.

Installation Notes

This tap is intended for use by machinists or maintenance technicians performing manual threading operations. Secure the workpiece firmly before tapping and use appropriate cutting fluid for the material being threaded. Apply steady, even pressure and back the tap off periodically to break chips and prevent binding. Do not force the tap if resistance increases, as high speed steel taps can fracture under excessive torque.
