It fits an 18mm fastener and measures 1-3\/32 inches in overall length, making it a compact option for tight-access fastener work. The hex drive style ensures positive engagement under high-torque conditions typical of pneumatic and electric impact tools. Built for trade professionals in mechanical, industrial, and maintenance applications, this socket is suited for technicians who demand reliable fastener engagement without rounding or slippage.\u003c\/p\u003e\u003cp\u003eThis socket is used across a wide range of professional applications including HVAC equipment assembly, plumbing fixture installation, and general mechanical maintenance where 18mm fasteners are common. The 3\/8 inch drive size positions it as a mid-range tool suitable for both bench work and on-site service calls. The 6-point design reduces the risk of fastener damage compared to 12-point sockets, making it a preferred choice when working with worn or tight hardware.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/8 inch drive fits standard 3\/8 inch impact wrenches and ratchets\u003c\/li\u003e\n\u003cli\u003e18mm socket size for metric fastener applications\u003c\/li\u003e\n\u003cli\u003e6-point contact geometry for secure grip and reduced fastener rounding\u003c\/li\u003e\n\u003cli\u003eHex drive style for positive torque transfer under impact loads\u003c\/li\u003e\n\u003cli\u003eCompact 1-3\/32 inch overall length for use in confined spaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 3\/8 inch drive impact socket compatible with 3\/8 inch drive impact wrenches, ratchets, and extension bars from any manufacturer following standard drive sizing.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall and remove using a 3\/8 inch drive impact wrench, air ratchet, or hand ratchet.
