The Multiquip 49243 is a genuine OEM Bolt Carriage Head 5/16" NF x 1" G5 designed for WSC55, R2000H, and WBH series equipment including WBH16, WBH16E, WBH16F, WBH16EF, WBH16EAWD, WBH16EAWDF, WBH21EFP, WBH21EF, and WBH21EPA models. Sourced directly from Multiquip, this fastener is manufactured to the same specification as the original hardware installed at the factory. Correct thread grade and dimensional accuracy matter on commercial equipment — using an undersized or off-grade bolt in a structural or mechanical joint can lead to fastener failure and costly downtime. Part number 49243 ensures you're installing the right Grade 5, fine-thread carriage head bolt every time.
Key Features
- Grade 5 Tensile Strength — Rated G5 for the clamping load demands found in power buggy frames, roller assemblies, and spray system mounts.
- Correct Thread Specification — 5/16" National Fine (NF) thread pitch matches original tapped hole specifications, ensuring full thread engagement without cross-threading.
- Carriage Head Profile — Smooth domed head and square neck lock the bolt in place against the mating surface, preventing rotation during installation and service.
- Genuine OEM Part — Supplied by Multiquip as a direct replacement, so dimensional tolerances, coating, and material grade align exactly with the original hardware.
- Broad Fitment Coverage — Confirmed for WSC55, R2000H static roller, and the full WBH series power buggies (WBH16, WBH21, and associated variants).
A carriage bolt is a through-fastener designed with a smooth, rounded head and a square shank section that seats into a matching hole to resist rotation without requiring a wrench on the bolt head. In equipment like power buggies and rollers, carriage bolts are commonly used to secure panels, guards, frames, and mechanical components where a flush or snag-free exterior surface is needed. When a carriage bolt stretches, shears, or strips its thread, the joint it holds can loosen under vibration and load — leading to accelerated wear on surrounding components or structural movement that affects machine handling and safety.
