Import 3/4" Hex Adaptors (Integral) — Buy in wholesale FOB from Supplier in India

Griphold Engineering Private Limited manufactures this 3/4-inch integral hex adaptor with a 1/2-inch square drive interface for direct power tool and ratchet connection. The tool is forged from chrome vanadium steel to the EN-47 specification, a material choice that delivers the torque-bearing capacity demanded by impact and heavy-duty applications. A black industrial phosphate finish replaces conventional chrome plating, offering rust resistance without surface peeling. The design follows IS standards for industrial tools, with 100% hardness testing carried out on every component after hardening and tempering.

EN-47 is a standard European grade of chrome vanadium steel containing approximately 0.50-0.55% carbon, with chromium and vanadium additions that improve hardenability and temper resistance. The material is subjected to stress relief prior to hardening, followed by controlled tempering to achieve the target hardness range typical for impact-rated sockets and adaptors in the 1/2-inch square drive category. The phosphate coating process deposits a crystalline manganese or zinc phosphate layer that provides both corrosion protection and lubricity during socket engagement, a finish specification common to military and industrial tooling but less so to commercial automotive brands.

This hex adaptor serves automotive workshops, maintenance contractors, and industrial facilities where Allen head fasteners are driven under power. The integral design (one-piece construction) eliminates theWeak point of pressed-together adaptor assemblies, making it suitable for high-torque impact wrench use. Buyers should confirm the exact overall length and hex opening depth with Griphold Engineering Private Limited to ensure clearance in recessed bolt applications. Export documentation is available; trade terms, Incoterms, and minimum order quantities should be discussed directly with the Vadodara-based supplier.

Griphold Engineering Private Limited operates from 309, Sanket Avenue, opposite Ambe Vidyalaya on Sama-savli Road in Vadodara, Gujarat, India. The supplier holds a harbor trust tier on the platform, with a response rate of 0.00% and zero recorded average response hours, indicating that direct enquiry may be required for timely communication. No employee count, revenue figure, or year of establishment is stated in the available profile.

The company's product focus centres on GRIPHOLD-branded industrial hand tools manufactured to Indian Standards (IS). Their stated manufacturing protocol includes pre-hardening stress relief, 100% hardness verification, and batch torque/load confirmation. The phosphate finish process is presented as a deliberate alternative to chrome plating, targeting applications where coating durability matters. Buyers should independently verify current production capacity, export licensure, and any ISO or BIS certifications not disclosed in the listing.
