Starrett S423Z Steel Stick Scale Set

This set of five small rules with improved holder is extremely useful for measurements in confined or hard-to-reach locations that prevent the use of ordinary rules. They are especially suitable for measuring grooves, short shoulders, recesses, keyways, and in tool and die work. The 4" long holder is well balanced, with the proper length for good reach. The rules are easily inserted in the slotted end of the holder and are rigidly clamped in place by a slight turn of a knurled nut. Two slots are provided, permitting the rules to be held at 30° or 45°, either square in a slot or tipped to one side. Thicknesses up to 1/16" can be clamped in either slot. Rules are made of thin, spring-tempered steel, with bright finish and highly accurate, machine-divided graduations. Each rule is graduated in 32nds of an inch on one side and 64ths on the reverse.
