SUGIFT 6-in Extra Long Allen Hex Bit Socket Set 18-Piece 3/8-in Drive S2 Alloy Steel Bits with CR-V 50BV30 Sockets SAE 1/8-in to 3/8-in and Metric 3-mm to 10-mm Sandblasted Mirror Polish with Black PE Case for Mechanics Auto Repair and Machinery Service

Extra-Long 6-in Bits: Extended 6-in hex bits reach deeply recessed fasteners in tight engine bays motorcycle suspensions and compact machinery where standard sockets cannot clear obstacles

S2 and CR-V Build: S2 alloy steel bits hardened to 56-62 HRC pair with CR-V 50BV30 sockets at 38-42 HRC to transfer high torque while resisting rounding breakage and corrosion

Chamfered Snug Fit: Rounded triangular contact points and chamfered edges widen bit-to-fastener contact so bits slide in smoothly and reduce rounded heads and slippage when tightening

SAE and Metric Coverage: Ten metric sizes from 3 to 10 mm and eight SAE sizes from 1/8 to 3/8 in serve automotive motorcycle bicycle appliance furniture and machinery work in a single kit

Drop-Resistant PE Case: Sandblasted mirror-polished bits store in a black PE case that grips each piece in a molded slot with size markings to prevent scattering and loss in transit
