P-06050100, P-06050075, P-06025075 & P-06025050 Individual 4-Way Steel Parallels
P-06050100, P-06050075, P-06025075 & P-06025050

  • These hardened steel parallels are ground to such close tolerances on four sides that there is no need to buy matched pairs for many common uses.
     

  • Can be used individually or matched with any other individual 4-way parallel at any time.
     

  • Different sizes can be used together. For example a 6" x 1/2" x 1" can be used with a 8" x 3/4" x 1" on the 1" dimension.
     

  • Held to size ±0.00025" on four sides.
     

  • Adjacent sides square within 0.0005" per inch.
     

  • Opposite sides parallel within 0.0001" per 6 inches.

4-WAY STEEL PARALLELS
P-06050100-M Matched Pair of 4-Way Steel Parallels
P-06050100-M


 

  • Made of alloy steel, hardened to Rc 58-62 and ground in matched pairs on four sides for use where extra precision is required.
     

  • Pairs are matched in size on the width and height to a tolerance of ±0.0002" on 6", 8" & 12" lengths and ±0.0003" for longer lengths.
     

  • Total parallelism, straightness over the full length is 0.0001" on 6" & 8" lengths, 0.0002" on 12" lengths & 0.0003" on longer lengths.
     

  • Adjacent ground sides are square with each other within 0.0004", except the 6" x 1/4" x 3/4", 6" x 1/4" x 3/8" and 6" x 1/4" x 1/2" sizes, which are square within 0.0005".
