Thread Gauge Set Helios Preisser Komplet MWGb Whitworth 28 pcs (MPN 0605103)

Helios Preisser Komplet MWGb is a 28-piece Whitworth thread gauge set designed for fast and reliable inspection and identification of Whitworth (W) thread forms. The set groups multiple gauge blades in a compact, organized holder to allow measurement of pitch and profile conformity for both internal and external Whitworth threads. It is intended for use in mechanical workshops, maintenance departments and quality-control stations where legacy or British Standard Whitworth fasteners are still in service.

Advantages

The set provides a comprehensive range of Whitworth sizes in a single, durable holder that reduces the need to carry individual gauges. Each blade is clearly marked for quick selection and the holder keeps gauges protected and aligned to simplify comparison and inspection. The compact format supports portability between workstations while materials and finish are chosen to withstand frequent handling in industrial environments.

Suitable for

• Inspection of Whitworth external and internal threads in mechanical assemblies
• Quality control in maintenance and repair shops handling British-standard fasteners
• Identification of pitch and profile conformity during refurbishment or restoration of vintage machinery
• Workshop use for fitting checks and troubleshooting threaded connections

Key specifications

• Set composition: 28 Whitworth thread gauge blades in a single holder
• Thread form: Whitworth (W) profile for both internal and external checks
• Marking: individual blade identification for quick size selection
• Holder: compact, protective organizer for storage and transport
• Application environment: workshop and quality-control use for mechanical components

How to use

Select the gauge blade matching the nominal size you need to check and insert it into the thread to see fit. For external threads, engage the appropriate blade along the crest and flank to check profile conformity and pitch agreement. For internal threads, insert the internal blade and verify that it engages the pitch and form without excessive play. Use the marked blade sizes to record the measured thread type. Clean threads and gauge blades before inspection to avoid false readings caused by debris or corrosion.

Usage recommendations

Store the gauge set in a dry environment and wipe blades after use to prevent corrosion. Use gentle hand pressure when checking threads to avoid damaging fine profiles. If repeated inspections are required, periodically verify the condition of the blades for wear and replace damaged blades to maintain measurement accuracy.
