Hand Tap Set FANAR 1/4" BSP inch threading, model A2-225801-3127, manual tap wrench included

FANAR hand tap set for 1/4" BSP inch threading is a manual threading kit designed to cut internal threads in metals and plastics. The set contains taps sized for standard 1/4" inch (BSP/inch) threads and includes a manual tap wrench that permits controlled, hand-operated threading. This compact set is intended for maintenance, repair and small workshop tasks where imperial-threaded holes are required.

Advantages

The set provides a straightforward and reliable method for creating or restoring internal 1/4" BSP inch threads without the need for powered equipment. The included manual tap wrench ensures gradual, controllable cutting and reduces the risk of tap breakage during hand operation. Components are suitable for use on common engineering materials such as steels, non-ferrous metals and many plastics when used with appropriate cutting fluid and correct technique.

Suitable for

• Manual thread cutting and repair of 1/4" BSP/inch threaded holes
• Workshop maintenance and general repairs requiring imperial threads
• Plumbing and fitting work using BSP/inch connections
• Small-scale fabrication and prototyping with metals and plastics

Key specifications

• Thread type: 1/4" BSP (inch) internal threads
• Set contents: multiple hand taps sized for 1/4" inch threads and a manual tap wrench
• Operation: manual hand-tapping with wrench for controlled torque
• Materials suitable for use: steels, non-ferrous metals, and many plastics
• Intended application: cutting or repairing internal threads in maintenance and workshop settings

How to use

Secure the workpiece in a vise or appropriate fixture so the hole is square and stable. Drill the correct pilot hole for a 1/4" BSP thread and chamfer the hole entrance if necessary. Fit the appropriate tap into the manual tap wrench, align the tap perpendicular to the hole, and turn the wrench clockwise with steady, even pressure to cut the thread. Back off the tap regularly to break and clear chips, and use suitable cutting fluid to reduce friction and improve finish. After tapping, clean the threaded hole of swarf and inspect the thread profile for correct engagement.

Usage recommendations

Use the correct pilot drill size and apply cutting fluid to extend tap life and improve thread quality. For brittle materials or through holes, clear chips frequently to avoid tap damage. If resistance increases significantly, reverse the tap slightly to break chips before continuing. Store the set in a dry place to prevent corrosion and ensure the wrench and taps remain true for accurate hand tapping.
