Value Collection DNFI043P5-050BX Acorn Nut 7/16-20 Unf

Product Description

The VALUE COLLECTION DNFI043P5-050BX is a standard acorn nut machined from Grade 2 steel with a nickel plated finish. Acorn nuts, also called cap nuts, feature a domed crown that covers the exposed end of a bolt or stud, protecting threads from contamination and providing a finished appearance on visible fastener locations. This nut carries a 7/16-20 UNF right-hand thread and measures 5/8 inches across the flats with an overall height of 11/16 inches. It is suited for general-purpose mechanical assembly in HVAC, plumbing, electrical, and light industrial applications where thread protection and corrosion resistance are priorities.

This acorn nut is used in a wide range of residential and commercial assembly scenarios, including equipment panels, brackets, enclosures, and any fastened joint where thread-end exposure is undesirable. The 7/16-20 UNF thread pitch is a fine-thread designation, providing tighter clamping force and better resistance to loosening under vibration compared to coarse-thread equivalents. The nickel plating adds a layer of corrosion resistance appropriate for indoor and lightly exposed environments. Tradespeople across mechanical, electrical, and plumbing disciplines encounter this fastener type during equipment installation and field fabrication.

Key Features

• 7/16-20 UNF right-hand thread for fine-thread engagement and vibration resistance
• Grade 2 steel construction provides adequate strength for general mechanical assembly
• Nickel plated finish adds corrosion resistance and a clean appearance
• Domed crown protects bolt or stud threads from damage and contamination
• 5/8 inch width across flats fits standard hex wrenches and sockets
• 11/16 inch overall height suits typical stud protrusion lengths for this thread size

Compatibility

Designed as a standard replacement or stock acorn nut for any 7/16-20 UNF threaded bolt or stud requiring a cap-style nut in general mechanical assembly applications.

Installation Notes

Installation requires a standard 5/8 inch hex wrench or socket. Verify that the mating bolt or stud thread specification matches 7/16-20 UNF before installation to avoid cross-threading. Shut down and de-energize any equipment before fastener service on live assemblies. Do not overtighten Grade 2 hardware beyond the torque values specified by the equipment manufacturer or relevant assembly standard.
