Description

Impact Socket 1-Inch Drive, 90mm High, Six-Point Profile

Brief Overview

This is a premium-grade impact socket engineered for professional pneumatic and electric impact tools. The 90mm depth positions it as a specialized tool for accessing recessed fasteners in heavy industrial, automotive transmission, and engine work. Built from chrome-molybdenum steel with thick-walled construction, this socket delivers the durability resellers need to justify bulk orders and build customer loyalty. Whether your shop specializes in heavy engine rebuilds or industrial maintenance, this socket is a cornerstone offering. Pair it with shorter-reach alternatives like the 80mm high socket or deeper applications with the 95mm profile to create a complete fastener solution for every job depth.

Key Features

  • 90mm Socket Depth: Reaches recessed fasteners in deep cavities, engine blocks, transmission housings, and industrial equipment
  • Six-Point Internal Profile: Grips fastener flats securely, minimizing cam-out and rounding damage on critical bolts
  • 1-Inch Square Drive: Compatible with all standard 1" drive impact tools and air/electric systems
  • Chrome-Molybdenum Construction: Superior impact resistance and fatigue strength for repeated heavy-duty cycles
  • Thick-Walled Design: Absorbs shock from impact tool operation without deforming or cracking
  • 124mm Outer Diameter at Drive End: Provides leverage and clearance in confined spaces typical of industrial assembly areas

Business Advantages for Resellers

  • High-Margin Item: Deep-reach impact sockets command premium pricing due to specialized application and durability requirements
  • Professional-Grade Specification: CR-MO steel construction justifies bulk purchasing by shops upgrading from consumer-grade tools
  • Recurring Demand: Transmission shops, engine rebuilders, and heavy equipment maintenance facilities require dedicated 90mm tools
  • Stock Completeness: This depth fills a critical gap in the 1-inch impact socket range, making your catalog indispensable to professional buyers
  • Minimal Returns: Industrial-grade construction means fewer warranty issues and higher customer satisfaction
