Details
Proto's J47148-SBD is an extensive, professional-grade 148-piece SAE Master Mechanics Socket Set designed for heavy industrial, automotive, and aerospace applications. This comprehensive kit features multiple drive sizes—1/4 inch, 3/8 inch, and 1/2 inch—to provide a versatile solution for virtually any fastening task. Each component is finished with a full polish chrome coating to ensure high-level corrosion resistance and durability in harsh work environments. Utilizing Proto's specialized TorquePlus™ internal design, the sockets engage the fastener flats rather than the corners, which minimizes rounding and allows for the safe turning of damaged or rusted hardware. This master tool set has a substantial product weight of approximately 31.45 pounds (14.26 kg).
