The Multiquip 32448 BHC Screw 5/16”-18 x 1/2” is a genuine OEM fastener designed for Whiteman walk-behind power trowel models including the JH55C, JH90C, JS60C, BH90C, BH11C, and BS90C. As a direct-from-Multiquip OEM component, part 32448 meets the exact thread specification and head geometry called out in the original equipment build. Stocking the correct fastener hardware ensures quick turnaround during scheduled maintenance or field repairs on your trowel.
Key Features
- Exact Thread Specification — 5/16”-18 UNC thread form and 1/2” grip length match the original torque and clamping requirements of the trowel assembly.
- Button Head Cap (BHC) Profile — Low-profile button head sits flush in confined fastener pockets common on walk-behind trowel guards and housings, eliminating interference with adjacent components.
- Genuine OEM Sourcing — Manufactured to Multiquip’s original material and hardness grade, ensuring the fastener holds rated clamp load across repeated torque cycles.
- Broad Trowel Family Coverage — Confirmed fitment across the JH55C, JH90C, JS60C, BH90C, BH11C, and BS90C Whiteman walk-behind trowel models.
- Prevents Loosening Under Vibration — A correctly specified fastener maintains joint integrity during the continuous vibration loads generated by walk-behind trowel operation, preventing component shift or damage.
A button head cap screw secures structural and guard components on the trowel by clamping mating parts together with a defined preload. The low-profile dome head distributes clamping force across a wider bearing area than a standard hex head, making it well suited to thin-panel mounting locations found on trowel housings. When a fastener is missing, under-torqued, or substituted with an incorrect thread pitch or hardness grade, joint movement under vibration can cause accelerated wear on mating surfaces, rattling, or outright component separation during operation.
