The most Premium Bit Holder Socket on the market.
The lightest, tightest fitting socket using the best materials and coatings.
Features of the TRO Superalloy Bit Holder Socket:
-
1/4" Hex Bit Holder machined from one of the strongest metals on Earth.
This "Superalloy" combined w/ extremely tight clearance fitment allows for the Ultimate in Ultralight design.
-
Our Superalloy material conforms to Mil-Spec, DFARS, Aerospace Material Specifications (AMS) and (3) GE Aviation Standards. Vacuum Induction Melted (VIM) followed by Vacuum Arc Remelting (VAR) ensures minimal impurities = exceptional fracture toughness.
-
Ultra-lightweight at 8.1 g (0.28 oz) total; 31-38% Lighter than other premium, slim design bit holders.
-
Exceptionally tight clearances. Both Hexes and the square drive offer much better fitment than standard tools. A near perfect fit on fasteners and hex bits.
- With minimal play between the socket and fastener, more of the socket is engaged, reducing stress on the tool.
- Extremely strong retention design on the 1/4" square drive.
