Value Collection R63033882 Hex Head Cap Screw 1/4-28

Product Description

The VALUE COLLECTION R63033882 is a 1/4-28 hex head cap screw machined from 18-8 stainless steel to a Unified National Fine (UNF) thread standard. It measures 1 inch under the head with a 7/16-inch hex drive. The 18-8 stainless steel construction provides solid corrosion resistance in wet, chemical, and moderate outdoor environments. This fastener is suited for mechanical assemblies, equipment enclosures, and structural connections where fine-thread engagement and stainless steel durability are required. Licensed tradespeople and maintenance technicians working in HVAC, plumbing, electrical, and general mechanical service will recognize this as a standard-inventory fastener for precision-fit applications.

This cap screw is appropriate for use in residential and commercial equipment assemblies where a fine-thread fastener is specified. The 1/4-28 UNF thread pitch provides greater thread engagement per inch compared to coarse-thread equivalents, making it well suited for thin-walled materials, vibration-prone assemblies, and applications requiring fine torque adjustment. It fits standard 7/16-inch hex drivers and wrenches.

Key Features

• 18-8 stainless steel construction for corrosion resistance in wet and chemically active environments
• 1/4-28 UNF thread for high thread engagement and vibration resistance
• 1 inch length under head for consistent, predictable clamping depth
• 7/16-inch hex drive compatible with standard hand and power tools
• Inch measurement system for direct drop-in use with standard SAE hardware

Compatibility

Designed as a standard 1/4-28 UNF hex head cap screw for use in equipment assemblies and mechanical applications specifying 18-8 stainless steel fasteners in the inch measurement system.

Installation Notes

Installation should be performed by a qualified technician or mechanic familiar with fastener torque requirements for 1/4-28 stainless steel hardware. De-energize or shut down any equipment before replacing or installing fasteners in live assemblies. Use a calibrated torque wrench to avoid galling, which is common with stainless steel threads — applying anti-seize compound to the threads before installation is a widely accepted practice. Follow applicable equipment manufacturer specifications and any relevant mechanical codes for the assembly type.
