Full & Partial Thread Steel Alloy, Plain Black Thermal Oxide PROFILE OF EXTRA STRENGTH Deep, accurate socket for high torque wrenching. Knurls for easier handling. Marked for easier identification. Head with increased bearing area for greater loading carrying capacity. Precision forged for symmetrical grain flow, maximum strength. Elliptical fillet doubles fatigue life at critical head-shank juncture. “3-R” (radiused-root runout) increases fatigue life in this critical head-shank juncture.

BODY

UNBRAKO “3-R” (RADIUSED ROOT RUNOUT)THREAD– Controlled radius of runout root provides a smooth form that distributes stress and increases fatigue life of thread run-out as a much as 300% in certain sizes.

CONVENTIONAL THREAD RUNOUT – Note sharp angle at root where high stress con centration soon develops crack which penetrates into body of the screw.
