3/8" Heavy Duty Double Hex Industrial Sockets

Griphold Engineering Private Limited manufactures these 3/8 inch square drive double hex industrial sockets under its GRIPHOLD brand at its facility in Vadodara, Gujarat. The sockets are forged from chrome vanadium steel conforming to EN-47 specification, selected for its fatigue resistance and ability to withstand repeated high-torque loading. A black phosphate industrial finish provides rust resistance without the peeling risk associated with decorative chrome plating. Every socket undergoes 100 percent hardness testing against IS-Standards for industrial hand tools, plus batch torque and load verification.

The double hex (12-point) geometry permits faster engagement with fasteners in confined spaces compared to standard hex profiles, though it demands tighter manufacturing tolerances to prevent rounding of fastener corners. Chrome vanadium EN-47 is a standard material for professional-grade impact and hand sockets in European and Indian tooling markets, offering a balance of toughness and wear resistance. Griphold's stated heat treatment sequence includes stress relief prior to hardening, followed by controlled tempering, a process sequence intended to minimise residual stresses that cause brittle fracture under impact. The phosphate coating thickness and coverage are typically specified to resist 24 to 48 hours salt spray exposure, though buyers should request the specific test protocol used.

These sockets serve maintenance departments in heavy machinery, oil and gas infrastructure, power generation, and automotive fleets where pneumatic or manual torque application requires tool reliability. The 3/8 inch drive size sits between light 1/4 inch and heavy 1/2 inch drives, making it the common choice for medium-duty assembly and repair. Importers should note that Griphold's product is positioned for industrial rather than consumer use, with testing protocols reflecting that duty cycle. Trade terms, minimum order quantities, and lead times are not stated in the available listing and must be confirmed directly with the supplier.

Griphold Engineering Private Limited operates from 309, Sanket Avenue on Sama-savli Road in Vadodara, Gujarat, India. The company holds a harbor trust tier on its marketplace profile, with a response rate currently showing 0.00 percent and zero average response hours recorded. These signals suggest limited or no recent engagement through the platform's inquiry system, so direct contact outside the platform may prove more reliable for urgent procurement timelines.

The supplier's profile focuses on its GRIPHOLD branded industrial hand tools, with particular emphasis on heat treatment, hardness testing, and phosphate finishing processes that differentiate its offering from general-purpose chrome-plated alternatives. The listing does not state year of establishment, production capacity, employee count, export experience, or specific client references. Buyers should request documentation of ISO 9001 or equivalent quality system certification, export licence status, and prior shipment references to assess operational scale and reliability.
