Value Collection 36976 Unequal Threaded Stud 1-3/4 in Alloy Steel

Product Description

The VALUE COLLECTION 36976 is an unequal double-end threaded stud designed for applications requiring different thread pitches or engagement lengths on each end. Made from grade 8 alloy steel with a yellow zinc dichromate finish, this stud delivers high tensile strength and corrosion resistance. The overall length is 1-3/4 inches, with a short-end thread of 7/16-14 (UNC, 3/4 inch long), a long-end thread of 7/16-20 (UNF, 7/8 inch long), and an unthreaded shank of 1/8 inch between the two threaded sections. Licensed tradespeople and mechanical assemblers install this type of fastener when fixed, headless threaded connections are required in tight or flush-mount assemblies.

Unequal-length threaded studs are commonly used in HVAC equipment mounting, plumbing fixture attachment, and general mechanical assemblies where a bolt head would interfere with clearance or where both ends must thread into separate components. The mixed UNC and UNF thread combination allows one end to engage coarse-threaded cast or fabricated components while the other seats in fine-threaded machined bores. This part ships in a package quantity of 25 and carries a minimum order quantity of 1 package, making it suitable for both single-job and stocking purposes.

Key Features

• Grade 8 alloy steel construction for high tensile and shear strength
• Yellow zinc dichromate finish provides corrosion and abrasion resistance
• Unequal thread design: 7/16-14 UNC short end (3/4 inch) and 7/16-20 UNF long end (7/8 inch)
• 1/8 inch unthreaded shank between threaded zones for precise positional control
• No flat (no wrench flats) — installed with a stud driver or double-nut method
• Package quantity of 25 per unit for job-site and shop stocking convenience

Compatibility

Designed as a standard double-end threaded stud for mechanical, HVAC, plumbing, and industrial assemblies requiring 7/16-inch fastener connections with mixed UNC and UNF thread engagement.

Installation Notes

Installation is performed using a stud driver or the double-nut locking method, as this part has no wrench flats. Ensure both receiving threads are clean, free of debris, and properly tapped to the correct pitch before driving. Apply appropriate thread lubricant or thread-locking compound per the assembly specification. Always torque to the fastener and joint specification for grade 8 hardware; do not over-drive into blind holes.
