功能

• 5~10 times longer than steel ring gauges.
• Screw ring gauge with aluminum outer ring.
• The outer ring acts as a guide when inserting.
• When inserting the workpiece, the inner diameter prevents the workpiece from falling down and makes it difficult to create "twisting."
• Even non-skilled workers can smoothly pass or fail work, improving work efficiency.
• Since the convenience of insertion is improved, it is recommended for processes such as total number judgment.
• The outer ring can be used as a protective ring to prevent the gauge from chipping when dropped.
• It is not slippery and can be handled with bare hands to improve work efficiency.
• The dirt on your hands does not adhere to the gauge.
