Cast heat-treated alloy illustrations are large toughness fasteners meant for probably the most demanding mechanical apps, with Unique alloy formulations out there which might be capable of retaining strength at temperatures in excess of a thousand degrees F (587 levels C).
Slotted and flat push heads are employed on applications that don't demand just as much torque as instruments can certainly slip from put.
This is analogous into the Phillips travel, but enhanced as it's a a lot less pronounced cross travel, which cuts down the slippage though allowing for the additional power to generally be applied.
