Value Collection C89466 Hex Cap Screw 1/4-28 X 2-3/4 in Grade 8

Product Description

The VALUE COLLECTION C89466 is a Grade 8 steel hex head cap screw with a 1/4-28 UNF thread and a 2-3/4 inch length under head. It features a zinc yellow dichromate finish that provides corrosion resistance and easy identification as a high-strength fastener. The shank is partially threaded, consistent with standard hex cap screw geometry for this length. Manufactured to ASME B18.2.1 dimensional standards, this screw is suitable for high-strength bolted joint applications where reliable clamping force and dimensional consistency are required. Sold in a package quantity of 50.

Grade 8 hex cap screws in the 1/4-28 UNF configuration are used across a wide range of mechanical and structural assembly applications, including HVAC equipment mounting, electrical enclosure fabrication, plumbing fixture brackets, and general industrial maintenance. The fine thread pitch of the 1/4-28 designation offers increased thread engagement and is well suited to applications where vibration resistance or precise torque control is needed. These fasteners are installed by mechanics, millwrights, HVAC technicians, electricians, and plumbers working on metal-to-metal joints in both residential and commercial settings.

Key Features

• Grade 8 steel construction provides high tensile and yield strength for demanding bolted joint applications
• 1/4-28 UNF fine thread for improved vibration resistance and thread engagement compared to coarse thread equivalents
• Zinc yellow dichromate finish delivers corrosion protection and visually identifies the fastener as high-strength Grade 8
• Partially threaded shank per ASME B18.2.1 standard hex cap screw geometry
• Packaged in quantities of 50 for bench stock, job lot, or MRO replenishment

Compatibility

Designed as a standard ASME B18.2.1 hex head cap screw for use with any 1/4-28 UNF tapped hole or matching nut where a Grade 8 high-strength fastener is specified.

Installation Notes

Install using a standard hex drive wrench or socket sized for a 1/4-inch hex cap screw head. Ensure mating threads are clean and free of debris before installation. Apply thread lubricant or thread-locking compound only as specified by the equipment manufacturer or applicable assembly documentation. Confirm fastener grade is appropriate for the joint design before use, as Grade 8 fasteners are not interchangeable with lower-grade hardware in high-stress applications.
