Value Collection R52001165 Serrated Flange Bolt 3/8-16 Unc

Product Description

The VALUE COLLECTION R52001165 is a serrated flange bolt designed for secure fastening in applications where the flange face must resist loosening under vibration. The bolt features a 3/8-16 UNC thread, a fully threaded shank with 1 inch of thread length under the head, and a hex drive for standard wrench or socket installation. The integrated serrated flange distributes clamping load across a wider bearing surface and bites into the mating material to resist rotation. Manufactured from AISI C1022 Grade 2 steel with a zinc-plated finish, this bolt suits general-purpose mechanical and structural assembly work across trades.

This bolt is used in general industrial, mechanical, and construction assembly where a standard hex bolt with a locking flange face is required. The serrated underside eliminates the need for a separate lock washer in many applications. Common installation scenarios include equipment frames, brackets, HVAC unit mounting, electrical enclosures, and light structural connections. The 3/8-16 UNC thread is one of the most widely used coarse-thread sizes in inch-standard fastener applications, making this bolt a routine stock item for maintenance and service operations.

Key Features

• Serrated flange face resists loosening under vibration without a separate lock washer
• Fully threaded shank with 1 inch of length under head for maximum thread engagement in thinner materials
• 3/8-16 UNC coarse thread for fast engagement and broad compatibility with standard nuts and tapped holes
• Hex drive accepts standard wrenches, sockets, and impact drivers
• Zinc-plated finish provides basic corrosion resistance for indoor and sheltered outdoor use
• Grade 2 AISI C1022 steel construction meets general-purpose mechanical fastening requirements

Compatibility

Designed as a general-purpose replacement or stock fastener for any application requiring a 3/8-16 UNC serrated flange bolt with 1 inch of length under head and a hex drive.

Installation Notes

Installation is performed with a standard hex wrench or socket sized for the bolt head. Power down or de-energize any equipment before accessing fastener points on electrical or mechanical assemblies. The serrated flange requires a clean, flat mating surface to function correctly — do not install over painted or coated surfaces where the serrations cannot seat into the base material. Follow applicable torque guidelines from the equipment manufacturer or relevant standards for 3/8-16 Grade 2 hardware.
