Thread Gauge Comb AWTools AWTOOLS SPRAWDZIAN 60° for Metric Threads, 24 Templates, 0.25–6.0 mm

Comb-style thread gauge AWTools AWTOOLS SPRAWDZIAN is designed for inspection of metric threads with a 60° profile. The tool contains 24 templates that cover a pitch or diameter range from 0.25 to 6.0 mm, enabling quick visual and tactile verification of both external and internal thread profiles. Compact and simple to handle, the gauge is intended for use in metalworking, maintenance, workshop quality control and repair tasks where fast identification of thread sizes is required.

Advantages

The comb design groups multiple thread templates in a single compact tool, reducing the need to carry separate gauges. Templates are arranged for straightforward selection and immediate comparison against screw threads or tapped holes. The 60° profile matches standard metric threads, allowing reliable visual and feel checks without complex measuring instruments. The tool is lightweight and easy to store in a toolbox or on a workbench for on-the-spot verification.

Suitable for

• Quick identification of external thread sizes on bolts and studs
• Verification of internal thread profiles in tapped holes
• Workshop quality control and incoming part inspection
• Maintenance and repair tasks in automotive and industrial settings
• General metalworking and machining projects requiring thread checks

Key specifications

• Thread profile: 60° metric
• Templates: 24 comb blades
• Coverage range: 0.25 mm to 6.0 mm (pitch/diameter)
• Material: durable metal blades with joined comb holder
• Form factor: foldable/comb-style for compact storage

How to use

Select the blade whose profile corresponds to the expected thread pitch or diameter and unfold it from the comb. For external threads, engage the blade directly with the screw or bolt and check for close contact along the flanks; for internal threads, insert the blade gently into the tapped hole and verify profile fit. Use visual alignment and tactile feel to determine whether the thread matches the template; a correct match will seat smoothly without significant gaps. After checking, fold the blade back into the comb to protect the templates.

Usage recommendations

Keep the comb clean and free of chips or lubricant before use to ensure accurate tactile verification. Use good lighting and, if necessary, a magnifier for small pitches. Store the gauge in a dry place to prevent corrosion and routinely inspect blades for wear or damage to maintain reliable checks over time.
