Description

1/4-Inch Drive E-Type Long Hand Socket, E4–E8 Sizes

Overview

This 1/4-inch drive E-type long hand socket is engineered for technicians and precision mechanics who require controlled, manual torque application in confined or sensitive assembly work. The extended length and external tamper-proof six-lobed profile make it ideal for tasks demanding accuracy over speed. Available in five sizes (E4 through E8), this socket delivers the repeatability your customers need for fastener-critical applications. Consider pairing this with compatible 6-point standard sockets for a complete 1/4-inch drive toolkit, or explore shorter E-type variants for applications requiring less reach.

Key Features

  • E-Type Six-Lobed Profile: External tamper-proof design prevents cam-out and provides superior grip on specialty fasteners; reduces rounding damage on sensitive hardware
  • Extended Length (50 mm): Long shank reaches recessed or hard-to-access fasteners without requiring extension bars
  • Knurled Grip Ring: Mid-socket knurled band enables precise finger-torque control for assembly-critical fastener work
  • Matte Nickel-Plated Finish: Corrosion-resistant surface suitable for diverse workshop environments
  • Precision Machining: Tight tolerances ensure repeatable engagement and minimal wobble
  • Single-Piece Construction: Solid metal body eliminates joint failure points

Business Advantages

  • Niche Demand: E-type sockets serve specialized industries (electronics assembly, precision manufacturing, OEM production) with limited competition—solid margin product
  • Bulk Order Friendly: Offer complete sets (E4–E8) to technicians upgrading hand tool kits; encourage multi-unit purchases across customer base
  • Controlled Inventory: Five sizes cover the majority of E-type fastener applications; minimal SKU complexity for distributors
  • Precision-Market Positioning: Market to electronics manufacturers, aerospace suppliers, and precision automotive shops where fastener control is non-negotiable
  • High Retention Value: Customers buying specialty sockets (E-type) tend to build complete tool collections—repeat order potential

Application Notes

  • Electronics & PCB Assembly: Manual torque control prevents component damage during delicate fastening
  • Precision Automotive: Specialty engine fasteners, sensor mounts, and control module assemblies
  • Medical Device Manufacturing: Sterile or sensitive assembly requiring exact fastener control
  • Optical & Instrument Assembly: Recessed fasteners in confined housings
  • OEM Production Lines: Hand-finishing fasteners on specialty hardware

Stock these in complete E4–E8 sets for bulk orders; position as a value-add bundle with standard 1/4-inch drive kits.
