Tekton SIB13205 3/8" Drive x 5.5 mm Hex Impact Bit Socket — $6.00
The Tekton SIB13205 3/8 inch drive x 5.5 mm hex impact bit socket is built for mechanics and DIYers driving hex fasteners with impact wrenches. At $6.00, it is the affordable, precise, impact-rated purchase for adding 5.5 mm hex capability to your socket set online.
Two-Piece Design
Tekton optimizes steel alloys, heat treatments, and forming for the bit and socket separately, then press-fits them permanently — a higher-performing, more durable result than one-piece bit sockets that will not loosen under stress.
Materials & Heat Treatment
The socket is made from 6140 chromium-vanadium steel heat-treated to 40–47 HRC for impact wrench use, with a manganese phosphate coating for corrosion resistance.
Precise Bit Geometry
The bit tip is machined to tight tolerances for an exact fit with hex fasteners, reducing cam-out and fastener rounding.
Compatibility
Smooth interior walls and a detent pin hole make this socket compatible with both friction ring and detent pin 3/8" drive anvils.
Size Markings
High-visibility laser marking plus a permanent stamped size marking ensure the 5.5 mm size stays readable.
Use Cases
Impact driving of hex-head bolts and fasteners in automotive, equipment, and mechanical assembly work.
