Import 3/8" Swivel Impact Sockets (Single Hex) — Buy in Bulk from Supplier in India

GRIPHOLD® 3/8 inch square drive swivel impact sockets are single hex impact-rated sockets manufactured from chrome vanadium steel conforming to EN 47 specification, finished with an industrial black phosphate coating rather than conventional chrome plating. The swivel design permits angled fastener access in confined spaces where straight sockets cannot operate, and the single hex profile delivers maximum contact area on hexagonal fasteners under impact loading. Each socket undergoes complete stress relief prior to hardening, with hardness controlled to IS-Standards for industrial hand tools and 100% inspection coverage.

The EN 47 chrome vanadium steel provides the toughness and fatigue resistance required for impact wrench applications, where peak torque loads can exceed static tightening values by significant margins. Heat treatment includes controlled austenitising, quenching, and a carefully monitored tempering cycle to achieve the target hardness range while retaining adequate ductility. The phosphate conversion coating offers functional rust resistance without the risk of peeling or spalling associated with electroplated finishes in high-impact service. Typical impact socket hardness for this class of tool falls in the 40-50 HRC range, though buyers should request the specific test report to confirm batch values.

These sockets target maintenance departments, automotive workshops, heavy equipment fleets, and industrial assembly operations where impact wrench use is routine. The 3/8 inch drive size represents the most versatile middle range, handling fasteners from approximately M8 to M16 depending on length and access constraints. Buyers should confirm minimum order quantities, available metric and imperial hex sizes in the swivel range, and whether Griphold provides individual replacement sockets or only set configurations. Packaging is typically bulk for industrial supply or plastic rail sets for retail distribution, but exact options require direct enquiry.

Griphold Engineering Private Limited operates from 309, Sanket Avenue, opposite Ambe Vidyalaya on Sama-savli Road in Vadodara, Gujarat, India. The company manufactures industrial hand tools under the GRIPHOLD® registered brand, with a product philosophy centred on heavy-duty applications rather than general-purpose consumer tools. The harbour trust tier and zero recorded response rate indicate limited platform engagement history, so buyers should expect to establish direct communication channels for quotations and technical support.

The supplier emphasises in-house heat treatment with IS-Standard compliance, 100% hardness inspection, and batch torque verification as quality controls. No information is provided about export experience, specific certifications beyond process adherence to Indian standards, production capacity, or client references. The phosphate finish versus chrome plating represents a genuine product-level differentiation, but buyers should request material certificates for EN 47 chemistry, heat treatment records, and third-party test reports to validate claims independently.
