Thickness Gages 245, 245M Engineers' Combina tion Taper, Wire and Thickness Gage INCH/MILLIMETER Consists of a wire gage, a taper gage for measuring slot widths, and an assortment of thickness gage leaves, all folding within a compact steel case. The gage measures 1/2" wide x 4-3/4" long (12.7 x 120mm) and has a locking device to lock any leaf or leaves in position. Both 245 and 245M have an English Standard wire gage leaf similar to our 188,but with shorter range, sizes numbered from 19-36 (.042-.004"), plus two additional sizes, 1/16" and 1/8".The reverse side has decimal equivalents in thousandths. 245 has a taper gage leaf for measuring slot widths from 1/64-3/16" in 64ths of an inch, the reverse side having a 3" scale graduated in 8ths and 16ths. It has nine thickness or feeler leaves as follows: .002, .003, .004, .006, .008, .010, .012, .015 and 1/16". 245M has a taper gage leaf for measuring slot widths from 0.5-5mm in 0.5mm, the reverse side having an 80mm scale graduated in mm and 1/2mm. It has eleven thickness or feeler leaves as follows: 0.04, 0.05, 0.06, 0.07, 0.08, 0.10, 0.15, 0.20, 0.30, 1 and 2mm. 806D with stock clamped on both ends 806 Thickness Gage or "Feeler" Stock Holders CLAMP AT ONE END 806D Thickness Gage or "Feeler" Stock Holders CLAMP AT BOTH ENDS These 806 Thickness Gage Holders provide a handy, convenient means of rigidly holding single leaves or strips of thickness gage stock of any thickness from .001-.025" (0.03-0.5mm). Stock up to 6" (150mm) long is easily inserted in the holder and firmly gripped in the desired position by a cam lock.This permits all of the stock to be used, because as it wears from use, the defective end can be snipped off and new stock pulled out until entirely used up. Available in two types as listed in the chart on the right, either to clamp stock at one end or both ends. Dull nickel finish. Size approximately 3/32" thick x 9/16" wide x 5-1/4" long (2.4 x 14 x 130mm). 806D holders have contrasting finish to eliminate the possible confusion on which end holds the thicker or thinner stock. 806 with stock clamped on one end Thickness Gage or "Feeler" Stock Holders Cat.
