Reach deeply recessed Allen fasteners in tight engine bays, machinery housings, and compact assemblies with an 18-piece extra long hex bit socket set on a 3/8 in drive. S2 alloy steel bits hardened to 56 to 62 HRC pair with chrome vanadium 50BV30 sockets at 38 to 42 HRC, balancing high torque transfer with break resistance under demanding fastening loads. Each bit measures about 6 in long to clear obstacles and engage screws that standard-length tools cannot reach, while chamfered edges and rounded triangular contact points slide in smoothly and reduce rounding of soft hex heads. The set covers ten metric sizes from 3 mm to 10 mm and eight SAE sizes from 1/8 in to 3/8 in, ready to handle automotive, motorcycle, bicycle, appliance, furniture, and machinery work without switching kits. A black PE drop-resistant storage case holds each bit firmly in its molded slot with size markings for quick identification, keeping the set organized in toolboxes, trucks, and workshops.
Extra Long 6 in Bits: Extended hex bit length reaches deeply recessed fasteners in tight engine bays, motorcycle suspensions, and compact machinery where standard-length sockets cannot clear obstacles
S2 Alloy Steel and CR-V Build: S2 alloy steel bits hardened to 56 to 62 HRC pair with CR-V 50BV30 sockets at 38 to 42 HRC for high torque transfer with reduced rounding and breakage
Chamfered Smooth Engagement: Rounded triangular contact points and chamfered edges expand bit-to-fastener contact area, sliding in smoothly while reducing rounded heads and slippage during tightening or removal
Versatile SAE and Metric Coverage: Suited for automotive repair, motorcycle service, bicycle assembly, furniture builds, appliance work, machinery maintenance, and general DIY across both imperial and metric fasteners
Drop Resistant PE Storage Case: Black PE case holds each bit firmly in a molded slot with clear size markings to prevent scattering and loss during transport between toolboxes, trucks, and workshop benches
