Multiquip 0243 SHC Screw 5/16-18 x 1-3/4

The Multiquip 0243 is a genuine OEM SHC Screw 5/16-18 x 1-3/4 designed for Whiteman and International ride-on power trowel models including the HHN, HTN, HTX, STX, and JWN series. This fastener is sourced directly from Multiquip to ensure correct thread specification, head geometry, and material grade for the original application. Confirmed fitment spans a wide range of machines including the HHN31V, HHN34TVD, HTX44Y5, HTX44K5, STX55Y6, STX55J6, HTN27K, HTN28K, and JWN24HTCSL, among others. Keeping the correct hardware in place is critical to maintaining the structural integrity of your trowel's assemblies.

Key Features

• Correct Thread Specification — 5/16-18 thread pitch and 1-3/4 inch length match the original hardware spec exactly, ensuring proper clamping force and engagement depth.
• Socket Head Cap Design — The SHC (socket head cap) profile allows installation with a hex key in tight clearances common on ride-on trowel frames and blade assemblies.
• Genuine OEM Sourcing — Manufactured to Multiquip's material and hardness standards, so the fastener performs consistently under the vibration loads typical of concrete finishing equipment.
• Broad Trowel Compatibility — Fits HHN, HTN, HTX, STX, and JWN series ride-on power trowels, covering both mechanical and hydrostatic Whiteman and International models.
• Correct Replacement for SP1G Saw Applications — Fitment data also confirms use on the SP1G flat saw, making this a versatile fastener across multiple Multiquip equipment families.

Socket head cap screws like the Multiquip 0243 are structural fasteners used to secure panels, guards, blade pitch assemblies, and frame components on ride-on power trowels. The socket head design provides a high-torque interface in a compact profile, making it well suited to confined assembly points where a standard hex bolt would not fit. When a fastener of this type is missing, stripped, or substituted with an incorrect size, it can compromise component alignment and introduce movement under the continuous vibration of trowel operation — making correct hardware replacement important to the safety and longevity of the machine.
