Description

Machine Screws Unslotted Indented Hex Washer Zinc Plated 1/4-20 X 5/8 are precision fasteners designed for reliable mechanical assembly in electronics, equipment, and machinery. This unslotted indented hex washer screw combines a hex drive with a built-in washer under the head for even load distribution and a durable zinc plating that resists corrosion.

  • Size / Thread: 1/4-20 UNC
  • Length: 5/8 in (16 mm)
  • Head type: Indented hex washer
  • Drive: Hex (unslotted)
  • Material / Finish: Steel with zinc plating

Key benefits include strong holding power, improved load distribution with a washer under the head, and enhanced corrosion resistance thanks to zinc plating. Suitable for a wide range of applications—from electronics enclosures to general machinery assemblies—where a dependable, standard-thread fastener is required.

Why choose these screws?

  • Durable zinc-plated finish protects against corrosion in indoor and light-industrial environments.
  • Indented hex washer head provides a secure drive and distributes pressure over a larger area to reduce pull-through.
  • Standard 1/4-20 UNC threading ensures broad compatibility with common tapped holes and nuts.
