This comprehensive 172-piece socket set uses the superior grip of the Super Lock profile for its shallow sockets and the standard 6-point profile for its deep sockets. With a good selection of 1/4″, 3/8″, and 1/2″ drive accessories and a hand ratchet for each drive size, this set will be a great addition to anyone’s tool collection. Super Lock sockets use a unique design, meaning the greater the torque applied, the more they will grip the nut or bolt—very handy for removing stubborn, worn, or rusty nuts and bolts. 1/4″ Drive 13 Shallow Super Lock Sockets: 4, 4.5, 5, 5.5, 6, 7, 8, 9, 10, 11, 12, 13, 14mm 7 Deep Sockets (Standard 6-Point): 4, 5, 6, 7, 8, 9, 10mm 5 E-Profile Sockets: E4, E5, E6, E7, E8 8 Star Bit Sockets: T8, T9, T10, T15, T20, T25, T27, T30 8 Tamper Star Bits: T8H, T9H, T10H, T15H, T20H, T25H, T27H, T30H 3 Pozi Screwdriver Bit Sockets: PZ0, PZ1, PZ2 3 Phillips Screwdriver Bit Sockets: PH0, PH1, PH2 4 Slotted Screwdriver Bit Sockets: SL4.5, SL5, SL6.5, SL7 4 Hex Bit Sockets: H3, H4, H5, H6 2 Extension Bars: 50mm & 100mm 1 Universal Joint 1 Sliding T-Bar (115mm) 1 Spinner Handle (150mm) 1 Bit Adapter for 1/4″ Hex Drive Bits 3/8″ Drive 10 Shallow Super Lock Sockets: 10, 11, 12, 13, 14, 15, 16, 17, 18, 19mm 6 Deep Sockets (Standard 6-Point): 10, 11, 12, 13, 14, 15mm 1 Spark Plug Socket: 14mm 6 E-Profile Sockets: E10, E11, E12, E14, E16, E18 1 Extension Bar: 125mm 1 Universal Joint 1 Bit Adapter for 5/16″ Hex Drive Bits 1/2″ Drive 17 Shallow Super Lock Sockets: 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 24, 27, 30, 32mm 5 Deep Sockets (Standard 6-Point): 16, 17, 18, 19, 22mm 2 E-Profile Sockets: E20, E24 2 Spark Plug Sockets: 16mm, 21mm 2 Extension Bars: 125mm, 250mm 1 Sliding T-Bar Handle 1 Universal Joint 1 Bit Adapter for 5/16″ Hex Drive Bits Ratchet Handles (72 Teeth, Quick Release) 1 1/4″ Drive Ratchet Handle 1 3/8″ Drive Ratchet Handle 1 1/2″ Drive Ratchet Handle 1/4″ Hex Drive Bits (25mm) 10 Torx Bits: T8, T9, T10, T15, T20, T25, T27, T30, T40, T45 4 Hex Bits: H3, H4, H5, H6 3 Phillips Screwdriver Bits: PH0, PH1, PH2 3 Pozi Screwdriver Bits: PZ0, PZ1, PZ2 5/16″ Hex Drive Bits (30mm) 6 Star Bits: T40, T45, T50, T55, T60, T70 6 Tamper Torx Bits: T40H, T45H, T50H, T55H, T60H, T70H 5 Hex Bits: H7, H8, H10, H12, H14 2 Phillips Screwdriver Bits: PH3, PH4 2 Pozi Screwdriver Bits: PZ3, PZ4 3 Slotted Screwdriver Bits: SL8, SL10, SL12 Hex Keys 7 Hex Keys: 1.5, 2, 2.5, 3, 4, 5, 6mm
