The Multiquip 49228 Round Head Bolt 1/4 NC 3/8 G2 is a genuine OEM fastener designed for WSC55 and MC44S series equipment. Sourced directly from Multiquip, this bolt meets the exact specifications required for a correct, secure fit. It is compatible with the WSC55 Chemical Spray System and the MC44S concrete mixer, making it a reliable choice for technicians servicing either machine. When you need a like-for-like replacement, the 49228 delivers the correct thread pitch, grade, and head profile straight out of the box.
Key Features
- Genuine OEM Grade 2 Construction — Manufactured to the same Grade 2 specification as the original bolt, ensuring correct tensile strength for the clamping loads this fastener was engineered to handle.
- Correct Thread Spec — 1/4 NC (coarse thread) profile matches the tapped holes in the host assembly exactly, eliminating the risk of cross-threading or improper engagement.
- Direct-Fit Replacement — Round head profile and 3/8 inch length match the original installation dimensions, so no rework or shimming is needed during reassembly.
- Verified Fitment — Confirmed for the WSC55 Chemical Spray System and MC44S concrete mixer; use part number 49228 to cross-reference against your machine's parts diagram before ordering.
- Structural Integrity at the Joint — A properly torqued Grade 2 bolt at the correct length maintains joint clamping force through vibration and load cycles; a worn or incorrect fastener can allow components to shift, loosen, or fail under operation.
A round head bolt is a structural fastener used to clamp and secure components within an assembly. The round head profile distributes load across a wider bearing surface compared to flat-head variants, making it well suited for applications where panel faces or housings must be held firmly without countersinking. The Grade 2 designation indicates the bolt's minimum tensile and yield strength rating, which determines how much clamping force it can safely sustain. When a fastener stretches, strips, or is replaced with an incorrect length or thread pitch, the joint loses clamping integrity — potentially causing misalignment, vibration-induced loosening, or component separation during operation.
