Value Collection 1512CH2 Hex Head Cap Screw 1/4-28 X 3/4 in

Product Description

The VALUE COLLECTION 1512CH2 is a fully threaded hex head cap screw designed for general-purpose fastening in mechanical assemblies, fixtures, and light structural applications. It features a 1/4-28 UNF thread — a fine-pitch designation suited for applications requiring precise torque control or vibration resistance compared to coarse-thread equivalents. The screw measures 3/4 inches in length under the head and is manufactured from Grade 2 steel with a zinc plating finish for moderate corrosion protection. It conforms to ASME B18.2.1 and SAE J429 standards, making it appropriate for use wherever dimensional and mechanical compliance to those specifications is required.

This cap screw is commonly used in light-duty mechanical and industrial assemblies including HVAC equipment panels, electrical enclosures, plumbing fixtures, and general trade hardware applications. The fine 1/4-28 UNF thread pitch is well-suited for thin-material fastening and applications where a secure, controlled fit is needed. The zinc-plated finish provides basic rust inhibition appropriate for indoor and sheltered environments. A 7/16-inch hex drive is required for installation.

Key Features

• 1/4-28 UNF fine-pitch thread for precise engagement and vibration resistance
• 3/4 inch length under head — fully threaded along entire shank
• Grade 2 steel construction meeting SAE J429 mechanical property requirements
• Zinc-plated finish for basic corrosion resistance in indoor and sheltered applications
• Conforms to ASME B18.2.1 dimensional standards
• 7/16 inch hex drive size for standard wrench or socket installation

Compatibility

Designed as a standard UNF hex head cap screw suitable for any 1/4-28 tapped hole application requiring an ASME B18.2.1 compliant fastener in Grade 2 steel with zinc plating.

Installation Notes

Install using a 7/16 inch open-end wrench, combination wrench, or socket driver. Ensure the mating tapped hole is clean and free of debris before threading to avoid cross-threading the fine UNF pitch. Do not exceed the mechanical load limits appropriate for Grade 2 steel in high-stress or critical-load applications — Grade 5 or Grade 8 fasteners should be selected for those uses. Follow applicable codes and equipment manufacturer torque guidelines for the specific assembly.
