Description

1/2-Inch Drive Hex Bit Socket, 4mm to 19mm, Chrome-Plated Steel

Brief Overview

This 1/2-inch drive hex bit socket delivers reliable, precise fastening for professional mechanics and technicians working with hexagonal socket-head cap screws and set screws. The chrome-plated steel construction provides durability and corrosion resistance, while the hardened hex bit ensures consistent engagement without stripping or rounding. Whether you're stocking individual sizes or building a complete socket collection, these sockets are essential for any professional shop. Pair them with complementary socket sizes to expand your fastening capabilities across different drive systems.

Key Features

  • 1/2-Inch Square Drive: Compatible with all standard 1/2-inch ratchets, extensions, and drive tools
  • Chrome-Plated Socket Body: Bright, corrosion-resistant finish resists rust and oxidation
  • Hardened Hex Bit: Dark-finished, heat-treated hexagonal bit resists wear and prevents cam-out
  • Knurled Grip Band: Textured collar allows secure hand handling during installation
  • 100mm Overall Length: Long enough for deep fastening without sacrificing control
  • Precision-Machined Construction: Tight tolerances ensure accurate fit and minimal wobble
  • Size Range: Available from 4mm to 19mm in 1mm increments (4, 5, 6, 7, 8, 10, 12, 14, 17, 19mm)

Business Advantages

Margin-Friendly Inventory: Individual SKUs allow you to stock high-demand sizes (5, 6, 8, 10mm) while offering complete size coverage. The standardized 100mm length simplifies stocking and cross-referencing across your catalog.

High Shop Velocity: Hex bit sockets are consumable-adjacent tools—they're small, affordable, and mechanics frequently replace worn bits. Bulk orders at competitive pricing unlock strong retail margins.

OEM Replacement Market: Many professional shops rebuy these sockets as part of routine toolkit maintenance, creating predictable repeat orders.
