Machined from alloy steel and finished in chrome, this standard-length socket is designed for professional hand-tool use in industrial maintenance, mechanical assembly, and similar trade applications. It meets ASME B107.1 standards, which sets dimensional and performance requirements for hand sockets. The 8-point geometry is specifically intended for driving square nuts, making it a purpose-built tool where a standard 6-point or 12-point socket would slip or fail to seat properly. Overall length is 1-5\/64 inches.\u003c\/p\u003e\n\u003cp\u003eThis socket is used wherever square nuts are encountered in mechanical, industrial, or maintenance work. Typical applications include structural fasteners, older mechanical equipment, utility hardware, and specialty assemblies that rely on square-nut fastening. It is well-suited for assembly-line technicians, maintenance mechanics, and field service professionals who need a reliable, standards-compliant socket for square fastener work. The chrome finish provides corrosion resistance for general shop and field use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e8-point socket geometry designed specifically for driving square nuts\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch drive compatible with standard ratchets, extensions, and torque wrenches\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASME B107.1 dimensional and performance standards\u003c\/li\u003e\n  \u003cli\u003eChrome plating provides corrosion resistance for shop and field environments\u003c\/li\u003e\n  \u003cli\u003eStandard length at 1-5\/64 inches overall for general-access fastener work\u003c\/li\u003e\n  \u003cli\u003eNot tether-capable — standard configuration without lanyard attachment point\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use socket for 3\/8 inch drive hand tool sets requiring an 8-point, 5\/16 inch square-nut socket.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall and remove fasteners with the drive fully seated in the socket to prevent rounding. Power down or de-energize any equipment before accessing fasteners in electrical or mechanical enclosures. Use a calibrated torque wrench when fastener specifications require controlled preload.
