Multiquip 29712-001 Carriage Bolt 1/4-20 x 3/4

The Multiquip 29712-001 is a genuine OEM Carriage Bolt 1/4-20 x 3/4 designed for a wide range of Multiquip and Whiteman equipment, including ride-on power trowels, hydrostatic trowel series, light towers, masonry saws, and water trailers. As a direct OEM replacement, 29712-001 is manufactured to the exact thread pitch, shank diameter, and head geometry specified for these machines, ensuring a flush, secure installation every time. Compatible models span the MD80, MD82, MD105, HTX6H, STX6H, HTXG6DF, HTXD6i, STXD6i, PRX, LT12, LT12D, SLT12D, MP1455H, MP120E, WT5HP, WTE5HP, and WT5C series, among others. Sourced directly through authorized Multiquip distribution channels, this fastener is the correct specification part to keep your equipment properly assembled and operating as designed.

Key Features

• Genuine OEM Fastener Grade — Manufactured to the exact thread specification (1/4-20) and length (3/4 in.) called out in Multiquip service documentation, ensuring correct clamping load and thread engagement.
• Broad Cross-Equipment Compatibility — A single stocked part number that services ride-on trowels (MD, HTX, STX, PRX series), light towers (LT12, SLT12D), masonry saws (MP and MS series), and water trailers (WT5, WTE5 series).
• Drop-In Installation — The domed carriage head and square neck seat directly into standard carriage bolt clearance holes used across these platforms, locking against rotation without additional tooling on the head side.
• Structural Integrity Where It Counts — A correctly torqued carriage bolt maintains panel, guard, and frame alignment; a missing or damaged fastener can allow components to shift under vibration, leading to accelerated wear or misalignment.
• Corrosion-Resistant Construction — Built to withstand outdoor exposure in concrete, asphalt, and water-management applications where equipment regularly encounters moisture, slurry, and debris.

A carriage bolt is a through-fastener designed to clamp two or more components together while resisting rotation during tightening. The rounded dome head bears against the outer surface of a panel or bracket, while the square shoulder beneath it bites into the material to prevent the bolt from spinning — allowing the nut to be tightened from one side only. On equipment like ride-on trowels, light towers, and masonry saws, carriage bolts are commonly used to secure guards, covers, frames, and structural brackets that experience constant vibration during operation. When a carriage bolt is sheared, corroded, or missing, the joint it holds can loosen progressively, causing component shift, noise, or — in the case of safety guards — an exposed hazard. Replacing a worn or damaged fastener with the correct OEM specification part restores the joint to its designed clamping condition.
