Value Collection MSC-04439451 Straight Flute Tap 14-24 Uns

Product Description

The VALUE COLLECTION MSC-04439451 is a straight flute tap designed for cutting 14-24 UNS internal threads in a wide range of materials. Built from high-speed steel (HSS) with a bright, uncoated finish, this tap delivers reliable performance in general-purpose threading applications. The bottoming chamfer allows threading to the bottom of blind holes, making it the right choice when full thread depth close to the hole floor is required. With 4 flutes and an H3 thread limit, it maintains dimensional accuracy and produces clean, consistent threads. Overall length is 2-5/8 inches, with a thread length of 1-1/4 inches. Right-hand thread direction is standard.

This tap is suited for machine shops, maintenance facilities, and production environments where 14-24 UNS bottoming threads are needed in blind or through holes. The HSS construction handles a broad range of workpiece materials including mild steel, aluminum, brass, and plastics. It is appropriate for use in manual tap handles or low-speed machine tapping setups. The bottoming chamfer style is specifically selected when threading must extend as close as possible to the bottom of a blind bore.

Key Features

• 14-24 UNS thread specification for unified national special thread form
• Bottoming chamfer for threading to the base of blind holes
• 4-flute design provides balanced cutting action and chip clearance
• High-speed steel construction for durability across a range of materials
• H3 thread limit for consistent dimensional control
• Bright, uncoated finish — no coating buildup to affect thread tolerance

Compatibility

Designed as an OEM-style replacement or direct-use tap for applications requiring 14-24 UNS right-hand internal threads with a bottoming chamfer profile.

Installation Notes

Machinists and toolroom technicians should ensure the workpiece is securely fixtured before tapping. Apply appropriate cutting fluid for the workpiece material to extend tap life and improve thread quality. When using in a blind hole, clear chips frequently to prevent tap breakage. Never reverse a bottoming tap under power without confirming the setup allows for controlled back-out.
