Value Collection D30007 Hex Head Cap Screw 1/4-20

Product Description

The VALUE COLLECTION D30007 is a 1/4-20 hex head cap screw intended for general mechanical assembly and maintenance applications across HVAC, plumbing, electrical, and industrial equipment. The fastener measures 1-3/4 inches under the head and carries a Grade 5 steel rating, making it appropriate for moderate-strength bolting tasks. A zinc-plated finish provides corrosion resistance in typical indoor service environments. The partial threading leaves a smooth shank section near the head, which helps maintain clamping force in through-bolt applications. Installers work with this fastener using a standard hex wrench or socket. It conforms to ASME B18.2.1 dimensional standards for inch-series hex cap screws.

This screw is suited for equipment panel assembly, bracket mounting, and field-service repairs where a 1/4-20 UNC fastener is specified. It is commonly used by HVAC technicians securing control box covers, mounting brackets, and access panels, as well as electricians fastening enclosure hardware. The partial thread design is appropriate for applications joining two components where the smooth shank spans a clearance hole in the first member.

Key Features

• 1/4-20 UNC thread for broad compatibility with standard tapped holes and nuts
• 1-3/4 inch length under head accommodates moderate stack thickness
• Grade 5 steel construction provides medium-strength clamping suitable for equipment assembly
• Zinc-plated finish resists corrosion in typical indoor service conditions
• Partially threaded shank maintains clamping load in through-bolt configurations
• Conforms to ASME B18.2.1 dimensional standard for consistent fitment

Compatibility

Designed as an OEM-style replacement or service fastener for any application requiring a 1/4-20 UNC hex head cap screw with a 1-3/4 inch length under head, Grade 5 rating, and zinc-plated finish per ASME B18.2.1.

Installation Notes

Installation should be performed with a properly sized hex socket or open-end wrench to avoid rounding the head. Power down or de-energize the equipment before accessing panels or enclosures secured by this fastener. Do not exceed the torque appropriate for Grade 5 fasteners in 1/4-20 applications as specified by the equipment manufacturer. Follow applicable codes such as NEC or IFGC when reinstalling electrical or gas equipment panels.
