Stainless-T-Drivers


SMT12-3 - 3mm x 12" Lg Shown)
Machined from 17-4 SS Heat Treated to RC-48, Chem-polished finish.
Metric Sizes: 2mm - 19mm
ST6-12 5/8 x 6" Lg (Shown)
Machined from 17-4 SS Heat Treated to RC-48, Chem-polished finish.
Fractional Sizes: 5/65 - 3/4

Note: This one-piece cushioned grip "T" handle driver is constructed of a round shank of 17-4 stainless steel with the hex machined on the end and is heat treated to R/C 45-48,

17-4PH is a martensitic precipitation hardening alloy which offers high strength and hardness while maintaining excellent corrosion resistant properties. In this it surpasses the 400 series, more closely resembling the corrosion resistant properties of type 304.

Type analysis of 17-4PH stainless steel

Carbon 0.07% max. Manganese 1.00% max Phosphorus 0.040% max
Sulfur 0.030% max Silicon 1.00% max Chromium 15.00/17.50%
Nickel 3.00/5.00% Copper 3.00/5.00% Columbium & Tantalum 0.15/0.45%

17-4 Stainless Corrosion Resistance:
Useful resistance to dry atmospheres, fresh water and mild alkalies and acids, but less resistant than the equivalent non-free-machining grades. Less corrosion resistant than the austenitic grades and also less than 17% chromium ferritic alloys such as Grade 430.
RoHS Compliant Products

These tools are made from 17-4 Stainless and are magnetic.
Fractional Sizes Note: Fractional sizes have a Red plastic coated cushion grip handle.
