Description

Engineered for durable metal-to-metal fastening, our Machine Screws Slotted Indented Hex Washer Zinc Plated 5/16-18 x 3 are designed to deliver a secure, corrosion-resistant hold in enclosures, machinery, and equipment. With a slotted drive, indented hex washer head, and zinc plating, these screws offer dependable performance in demanding environments.

Key Features

  • Size / Thread: 5/16-18 UNC
  • Length: 3 inches
  • Drive Type: Slotted
  • Head Style: Indented Hex Washer
  • Material & Finish: Zinc-plated steel
  • Standard: Unified National Coarse (UNC)

These machine screws are ideal for fastening metal parts where a broad load-distributing head is important. The hex washer head helps prevent pull-through and provides a larger bearing surface, while the zinc plating provides corrosion resistance in mildly corrosive environments or exposed applications. The slotted drive is compatible with standard flat-blade drivers for easy installation and removal, making them a versatile choice for electrical panels, control boxes, machinery housings, and equipment assemblies.
