Multiquip 0105 Screw HHC 5/16-18 x 1-1/2

The Multiquip 0105 is a genuine OEM Screw HHC 5/16-18 x 1-1/2 designed for a wide range of Multiquip and Whiteman power trowels, masonry saws, screeds, and concrete vibrators. As a direct OEM replacement, this fastener is manufactured to the exact thread pitch, grip length, and head dimensions called out in Multiquip factory parts documentation. Verified fitment spans ride-on trowel models including HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, STX55J6, STX55Y6, HHN31V, and HHN34TVD, as well as walk-behind trowel series such as CA, JA, B, BA, J, and HDA. Compatibility also extends to masonry saw models including MP1455H, MP1415E, MP1420E, MS1455H, MS1415E, and MS1420E, plus screeds and select concrete vibrator models.

Key Features

• Genuine OEM Thread Specification — Manufactured to the exact 5/16-18 UNC thread form and 1-1/2 inch grip length, ensuring correct torque engagement and secure clamping across every application this fastener is called out for.
• Hex Head Cap Design — The HHC hex head allows standard wrench or socket access for straightforward installation and removal during routine service, reducing the risk of fastener damage during maintenance cycles.
• Broad Cross-Equipment Fitment — A single OEM part number covers ride-on trowels (HTX44, STX55, HHN31, HHXD5, HHXG5), walk-behind trowel series (CA, J, JA, B, BA, HDA), masonry saws (MP1455H, MS1455H, TRAK-14), screeds (PSH), and concrete vibrators (G55H), minimizing the number of fastener SKUs needed on the job.
• Correct Clamping Load for Structural Joints — Using the specified OEM fastener maintains the designed clamp load on housings, guards, and structural brackets. An incorrect substitute fastener — wrong pitch, length, or grade — risks joint loosening under machine vibration.
• Direct OEM Source via DHS Equipment — Sold by DHS Equipment as a genuine Multiquip OEM part, so the part number, specification, and fitment data align precisely with Multiquip service manuals and parts diagrams.

A hex head cap screw is a structural fastener used to clamp two or more components together at a fixed, controlled load. In power trowels, saws, and screeds, fasteners like the 0105 secure housings, blade guards, engine mounts, and structural covers that must remain firmly in place under continuous vibration and mechanical stress. When a fastener stretches, strips, or is replaced with an incorrect substitute, joint integrity is compromised — components can shift, vibrate loose, or allow debris ingress into critical areas. Using the correct OEM-specified fastener ensures the joint performs as the machine was engineered to operate.
