G 1/2" x 14 HSS Tap Hand Threading Tool For Pipe Threads DIN ISO 228, 16mm Shank - TECWERK

Take advantage of the combination of durable HSS cutting steel, a 16 mm shank for stable clamping and the BSP parallel G 1/2" × 14 thread form to ensure consistent pipe-thread production; order or request advice through Metav Werkzeuge for reliable supply and application support.

TECWERK hand tap DIN 5157 No.2 G 1/2" × 14 HSS (BSPP, 16 mm shank)

A TECWERK hand tap for cutting BSP parallel (G) pipe threads, intended for through and blind holes and optimised for steels up to approximately 900 N/mm².

• HSS cutting steel for durable performance
• BSPP G 1/2" × 14 thread per ISO 228
• Suitable for through and blind holes
• 16 mm shank diameter for stable clamping

Reliable thread creation with industrial efficiency

The TECWERK hand tap DIN 5157 No.2 is designed for consistent, repeatable results in pipe-thread production. Manufactured from HSS, the tool retains edge integrity under moderate thermal and mechanical loads, which reduces the need for frequent regrinding and supports higher throughput. The combination of a parallel BSP (G) thread form compliant with ISO 228 and the 14 threads-per-inch pitch provides compatibility with standard fittings, while the right-hand geometry ensures conventional cutting behaviour and predictable chip evacuation for efficient manual or machine-assisted tapping.

Stable clamping and clear material limits for process planning

A robust 16 mm shank offers secure clamping in standard toolholders, diminishing vibration and improving concentricity during tapping operations. The cutting geometry is suited to steels with tensile strengths up to about 900 N/mm², which covers a wide range of structural and engineering steels; this classification helps planners select the tap where performance and tool life are optimised. Because the material and geometry are specified, decisions on cutting speeds and lubricants can be made with precision, resulting in fewer rejects and smoother production cycles.

Standards-compliant design for versatile shop-floor use

Conformance to DIN 5157 No.2 and the ISO 228 thread specification means the tool integrates seamlessly into existing production processes and inspection routines. The tap is designed for both through and blind holes, enabling flexibility across assemblies. The right-hand cutting action promotes controlled chip flow; when paired with appropriate cutting fluid and a correctly sized pilot hole, the result is a clean thread profile with minimal secondary finishing. Clear technical conformity reduces uncertainty during procurement and supports quality assurance documentation.

FAQ

What thread form does this tap produce?
The tap cuts a BSP parallel thread (G) in the G 1/2" × 14 configuration in accordance with ISO 228; the thread form is suitable for standard parallel pipe fittings.

Which materials are suitable for use with this tap?
The tool is made of HSS and specified for use in steels up to approximately 900 N/mm² tensile strength; other materials are not listed in the product data.

Can the tap be used for blind holes?
Yes, the design supports both through and blind hole tapping operations without modification.

What is the shank size and why does it matter?
The shank diameter is 16 mm, which gives secure clamping in common holders and improves stability and concentricity during tapping.

Does the product conform to any standards?
The tap is specified as DIN 5157 No.2 and the thread form follows ISO 228 for BSP parallel (G) threads.
