Key Features
- Grade 5 Structural Integrity — Rated to Grade 5 tensile strength, this fastener delivers the clamping force required for secure, vibration-resistant assembly in demanding pump applications.
- Correct Thread Specification — 3/4 NC (National Coarse) thread form ensures proper engagement with mating threads, preventing cross-threading and maintaining clamping load over the service life of the fastener.
- OEM-Specified Dimensions — At 3-1/2 inches in length, EM492421 matches the exact bolt length called out in Multiquip service documentation, so there is no risk of under-engagement or interference with surrounding components.
- Confirmed Fitment for Trash Pump Series — Verified for use on Multiquip Trash Pump models, giving you confidence you are ordering the right part the first time.
- Pump Assembly Reliability — A correctly torqued, properly graded fastener keeps pump housings, flanges, and mounting brackets sealed and aligned under the sustained vibration loads that trash pumps generate during operation.
A hex head cap screw like the EM492421 serves as a primary structural fastener, drawing mating components together and maintaining the clamping load that keeps assemblies sealed and properly aligned. In trash pump applications, fasteners are subjected to continuous vibration, fluid pressure, and thermal cycling, all of which can cause undertorqued or incorrect-grade bolts to loosen or fail over time. Using the OEM-specified Grade 5 fastener at the correct length and thread pitch ensures the assembly performs as designed and prevents costly leaks or structural failures in the field.
