Multiquip 22135 SHC Screw 1/2-20x1.50 NP

The Multiquip 22135 SHC Screw 1/2-20x1.50 NP is a genuine OEM fastener designed for ride-on power trowel models including HTNS5S-2, EHHNK5, and HHNG5. As a direct OEM component sourced from Multiquip, this screw meets the exact thread pitch, length, and material specification required for a secure and correct installation. Keeping the right hardware in your trowel is essential — undersized or incorrect fasteners can lead to loosening under vibration and cause costly mechanical failures. Verify your model number against the fitment list before ordering to ensure compatibility.

Key Features

• Genuine OEM Thread Specification — Manufactured to the exact 1/2-20 thread pitch and 1.50-inch length called out in the Multiquip parts schema, ensuring proper torque engagement and thread integrity.
• Drop-In Hardware Replacement — Socket head cap (SHC) profile matches the original mounting point geometry on ride-on power trowel assemblies, seating correctly without rework.
• Confirmed Fitment — Verified for HTNS5S-2, EHHNK5, and HHNG5 Multiquip ride-on power trowels; always confirm your model and serial plate before ordering.
• Vibration-Resistant Fastening — Correct thread engagement at the specified pitch prevents loosening under the continuous rotational forces generated by power trowel blade operation, protecting surrounding components.
• NP Finish for Durability — Non-plated (NP) finish is specified to suit the installation environment on these trowel models, matching the original hardware standard.

A socket head cap screw (SHC) is a high-strength fastener with a cylindrical head driven by an internal hex key, commonly used in mechanical assemblies where a low-profile, high-torque connection is required. On ride-on power trowels, fasteners like the 22135 secure critical structural and mechanical components that must remain tight through sustained vibration and heavy working loads. When a fastener of the wrong thread pitch, length, or grade is used, it can strip threads, back out during operation, or fail to clamp components correctly — leading to accelerated wear or component damage that far exceeds the cost of the original screw.
