从India供应商批量进口3/8" Crow Foot Wrenches

This GRIPHOLD branded crow foot wrench features a 3/8 inch square drive interface designed for torque wrench and ratchet extension access in confined spaces where conventional sockets cannot reach. Manufactured from chrome vanadium steel grade EN-47, the tool undergoes a controlled heat treatment sequence including stress relief prior to hardening, with final hardness aligned to Indian Standard IS specifications for industrial hand tools. The black phosphate surface finish provides rust resistance through chemical conversion rather than electrolytic deposition, giving a non-peeling surface suited to oily workshop environments where chrome plating would flake under mechanical abrasion.

The EN-47 material is a standard Indian grade of Cr-V steel with typical composition around 0.45-0.55 percent carbon, 0.90-1.20 percent chromium, and 0.10-0.25 percent vanadium, offering high hardenability and temper resistance for impact-rated hand tools. Griphold's stated manufacturing sequence places particular emphasis on stress relief before austenitising, reducing distortion during quenching, and controlled tempering to achieve the target hardness range without excessive brittleness. The phosphate coating process generates a crystalline iron-zinc-manganese phosphate layer that retains lubricating oil and resists red rust in humid conditions, though it offers less decorative appeal than chrome plating.

Target buyers include maintenance departments in heavy engineering, oil and gas field services, power plant overhaul contractors, and railway workshop facilities where torque-controlled fastening in restricted access is routine. The crow foot geometry allows the open-end jaw to engage hexagonal fasteners while the drive tang accepts calibrated torque tools, critical for hydraulic fitting, cylinder head, and structural bolt applications. Importing from Vadodara, Gujarat, buyers should confirm with Griphold Engineering their current production capacity, standard packing unit quantities, and whether torque/load test certificates accompany each batch or are available on request.

Griphold Engineering Private Limited is headquartered at 309, Sanket Avenue, opposite Ambe Vidyalaya, Sama-savli Road, Vadodara, Gujarat, India, 390024. 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, suggesting that direct enquiry may be necessary to establish communication reliability. No verified year of establishment, annual revenue, employee count, or named client references are present in the available data.

The supplier's profile emphasises heavy-duty industrial tool manufacturing with a specific focus on higher torque and impact applications, differentiating from general-purpose chrome-plated tools through phosphate-finished products with claimed double the wear resistance. The manufacturing narrative centres on heat treatment discipline and 100 percent testing compliance to IS standards. Buyers should independently verify Griphold's ISO 9001 or equivalent quality system registration, request factory inspection access in Vadodara, and confirm whether the torque/load testing is conducted in-house or through accredited third-party laboratories, as these factors determine consistent batch quality for industrial procurement.
