Value Collection D39472 Hex Cap Screw 3/4-16 X 2 in Grade 8

Product Description

The VALUE COLLECTION D39472 is a fully threaded hex head cap screw designed for high-strength fastening applications. Manufactured from Grade 8 steel with a zinc yellow dichromate finish, this fastener delivers the corrosion resistance and mechanical strength required in demanding industrial and mechanical assembly environments. It features a 3/4-16 thread size conforming to UNF (Unified National Fine) standards and measures 2 inches under the head. The zinc yellow dichromate coating provides a dual layer of protection against oxidation and galvanic corrosion, making it suitable for both indoor and outdoor installations. Compliance with ASME B18.2.1 ensures dimensional accuracy and load consistency across production and service applications.

This cap screw is used across a wide range of mechanical, industrial, and trade applications where fine-thread, high-tensile fasteners are required. Grade 8 fasteners are commonly specified in structural assemblies, heavy equipment, HVAC equipment mounting, and machinery where shear and tensile loads exceed the capacity of lower-grade hardware. Fully threaded construction makes this screw well suited for through-bolt applications and thinner material joints that benefit from maximum thread engagement. Licensed trades including millwrights, pipefitters, and general contractors routinely specify Grade 8 UNF fasteners for these scenarios.

Key Features

• Grade 8 steel construction provides high tensile and proof load ratings for heavy-duty fastening
• Zinc yellow dichromate finish offers corrosion resistance beyond standard zinc plating
• Fully threaded shank maximizes thread engagement in through-bolt and thin-material assemblies
• 3/4-16 UNF thread delivers finer pitch for improved clamp load and vibration resistance versus UNC
• Meets ASME B18.2.1 dimensional standard for consistent fit and interchangeability
• Hex drive head is compatible with standard 1-1/8 inch hex wrenches and impact sockets

Compatibility

Designed as a standard 3/4-16 UNF hex head cap screw for use in any application requiring an ASME B18.2.1-compliant Grade 8 fastener of this thread size and length.

Installation Notes

Installation should be performed by a qualified technician familiar with proper torque procedures for Grade 8 UNF fasteners. Always de-energize and lock out any powered equipment before replacing or tightening fasteners in mechanical assemblies. Use a calibrated torque wrench to achieve the specified clamp load for 3/4-16 hardware in the applicable equipment service manual. Inspect mating threads for damage or contamination before installation to avoid false torque readings.
