Features:

Instead of juggling multiple gauges, this one comprehensive set puts every pitch you need at your fingertips. Reduces tool crib clutter and makes your workflow smoother with zero guesswork on which gauge to grab.
Ideal for fast thread identification, checking lathe tool angles, and verifying thread cutting tool geometry. A must-have for machinist, maintenance pros, and product inspectors alike.
Equipped with both 55 degree (Whitworth) and 60 degree (Unified / Metric) thread angles, this gauge ensures accurate readings across virtually any screw profile or cutting tool you encounter in daily shop work.
Crafted from stainless steel with a brushed, wire-drawn finish that resists rust and corrosion. Engineered to withstand drops, daily wear, and harsh workshop conditions – keeping its precision for years.
- Includes Metric (0.25–6.0 mm), Imperial (4G–62G), and US TPI (8–28) in a single set. From fine to coarse, this all-in-one gauge eliminates the need to buy separate tools – saving you time right out of the box.

Place of Application: Used for checking tool angle while cutting threads in metal turning lathes, accurately measures internal and external screw threads with thread blades of varied size.
