Minerallac 55009J Cap Screw 1/4-20 X 1/2 Inch Grade 5

Product Description

The MINERALLAC 55009J is a Grade 5 cap screw with a 1/4-20 thread size and 1/2 inch length. Cap screws of this type are externally threaded fasteners used to clamp or secure components in electrical, mechanical, and HVAC assemblies. The Grade 5 rating indicates medium-strength carbon steel construction with a tensile strength suitable for general industrial and trade applications. This fastener is installed by electricians, HVAC technicians, and mechanical contractors wherever a reliable threaded fastener connection is required in panel, equipment, or structural assemblies.

This cap screw is suited for use in residential and light commercial installations where a 1/4-20 threaded fastener is specified. Common applications include securing electrical enclosures, equipment panels, conduit supports, HVAC equipment frames, and other mechanical assemblies that require a standard hex-head or socket-head cap screw in the 1/4-20 thread pattern. The 1/2 inch length makes it appropriate for thin to medium material stack-ups.

Key Features

• 1/4-20 thread size for compatibility with standard 1/4-20 tapped holes
• 1/2 inch length suitable for thin to medium material thicknesses
• Grade 5 rating indicating medium-strength carbon steel construction
• Lightweight at 0.01 pounds per fastener for easy handling and inventory

Compatibility

Designed as an OEM-style replacement or standard-stock fastener for assemblies requiring a 1/4-20 x 1/2 inch Grade 5 cap screw in electrical, HVAC, plumbing, or mechanical equipment applications.

Installation Notes
