Value Collection MSC-04463212 Straight Flute Tap 7/16-20 Unf

Product Description

The VALUE COLLECTION MSC-04463212 is a straight flute bottoming tap designed for cutting 7/16-20 UNF right-hand internal threads in through or blind holes where full thread depth close to the bottom is required. Manufactured from high-speed steel with a bright/uncoated finish, this tap delivers reliable cutting performance across a range of ferrous and non-ferrous workpiece materials. With 4 flutes and an H2 thread limit, it holds close tolerances suitable for general-purpose threading applications in production and maintenance environments. The 1-7/16 inch thread length and 3-5/32 inch overall length make it compatible with standard tap handles and machine setups.

This tap is suited for machinists, maintenance technicians, and toolroom operators working on equipment repair, fixture fabrication, or component production. The bottoming chamfer geometry allows threading to within 1-2 threads of a blind hole bottom, making it the correct choice when a plug or taper tap has already been used to start the thread or when through-thread depth is critical. It is appropriate for use in manual tap handles, drill presses, and tapping machines in both shop and field settings.

Key Features

• Bottoming chamfer for threading to near the base of blind holes
• 7/16-20 UNF thread form with right-hand direction
• 4 straight flutes for chip clearance in standard threading operations
• High-speed steel construction for durability across common workpiece materials
• H2 thread limit for consistent, close-tolerance thread fits
• Bright/uncoated finish — no coating buildup to affect thread sizing

Compatibility

Designed as a standard replacement or general-purpose bottoming tap for any application requiring a 7/16-20 UNF right-hand internal thread with an H2 thread limit.

Installation Notes

This tap should be installed and operated by a qualified machinist or maintenance technician familiar with threading tool procedures. Always ensure the workpiece is securely clamped and the tap is properly aligned to the hole axis before beginning the threading operation to prevent tap breakage. Apply appropriate cutting fluid for the workpiece material, and back off periodically to break chips when tapping by hand. Follow applicable shop safety standards when operating tapping machines or drill presses.
