Precision Angle Measurement

The General Tools 17 protractor provides permanently etched graduations from 0 degree to 180 degrees in opposite directions. Machinists, drafters and mechanics rely on its ground stainless steel construction for repeatable layout work.

Adjustable Arm Functionality

A 6 inch protractor arm locks into the required angle with a knurled thumb nut. The square head style allows the tool to register against a workpiece edge while the scale remains readable from either side.

Stainless Steel Durability

Ground stainless steel resists corrosion and wear in shop environments. The 3-3/8 inch by 2 inch head offers a stable reference surface without adding bulk to a tool chest or bench.

Questions about this item

Will the knurled thumb nut on the 6-inch arm need periodic tightening?

The knurled thumb nut locks the adjustable 6-inch arm into the desired position and can be re-tightened by hand whenever the setting shifts.

At what angle does the graduated scale stop reading?

The permanently etched graduations run from 0 degree to 180 degrees in opposite directions, so the scale ends at 180 degrees.

Does the ground stainless steel head get hot during prolonged layout work?

The protractor is made of ground stainless steel with no moving parts that generate heat, so it remains at ambient temperature during use.
