Buyers Products UB623524 24ft Square Bend U-Bolt Kit - Durable Grade 5

In this review the Buyers Products UB623524 24' Square Bend U-Bolt Kit is evaluated for mechanics and fleet owners who need a straightforward solution for mounting truck boxes and connecting bodies to chassis. The bottom line: this kit delivers the most important benefit - simple, strong hardware - because it packages four 5/8 in. square bend U-bolts with forged 1/2 in. tie bars and Grade 5 equivalent components that make installation fast and reliable for most truck frames.

Key Features

• Complete kit: Includes four 5/8 in. square bend U-bolts, eight hex nuts, and split lock washers so installers have what they need for a single box mounting job without sourcing extra fasteners.
• Forged tie bars: The 1/2 in. thick forged steel tie bars provide superior strength and resist bending under load, important when securing heavy truck bodies.
• Grade 5 equivalent hardware: Hardware rated to Grade 5 equivalent strength balances durability and cost for demanding chassis connections.
• Versatile lengths: Available in various lengths to accommodate different truck chassis dimensions, which helps achieve a secure fit across applications.
• Easy installation: Standard 5/8 in. U-bolt diameter and included nuts and lock washers reduce fitment guesswork and speed installation on common frames.

Who It's For

This kit is best for fleet managers, service shops, and vehicle owners who mount service boxes, toolboxes, or body components to medium and heavy duty truck frames and need reliable, replaceable hardware. Installers who prefer a single packaged solution with forged tie bars and Grade 5 equivalent fasteners will appreciate the convenience and strength.

Those who should look elsewhere include technicians requiring stainless steel or specially coated hardware for corrosive environments, or users who need metric fasteners or nonstandard thread forms, as this kit is designed around Imperial sizes and conventional Grade 5 equivalent materials.
