The Multiquip 915003 Hex Head Cap Screw 1/4-20 x 3/4 Grade 8 is a genuine OEM fastener designed for SP series pavement saws, MG30 series fireproofing pumps, and MG30 mixers. As a Grade 8 rated fastener, it delivers the tensile strength required for structural and load-bearing connections on demanding equipment. This screw is a verified direct replacement, confirmed to fit SP303516, SP303520, SP303526, SP303530, SP4, SP605716, SP605720, SP605726, SP605730, SP605736, SP6457, MG30T2D, MG30M2D, MG30T3D, MG30M3D, and MG30 models. Having the correct fastener on hand keeps your equipment properly assembled and performing as designed.
Key Features
- Grade 8 Tensile Strength — Hardened to Grade 8 specification, this screw handles high-stress clamping loads without stretching, stripping, or loosening under vibration.
- Genuine OEM Part — Sourced directly from Multiquip, this fastener matches the exact thread pitch, grip length, and head dimensions of the original hardware installed at the factory.
- Broad Fitment Across SP and MG30 Series — Confirmed fit for SP series pavement saws including SP303516, SP303530, SP605730, and SP6457, as well as MG30 series fireproofing pumps and mixers.
- Vibration-Resistant Clamping — Designed for equipment that operates under continuous vibration, the Grade 8 rating resists self-loosening and maintains joint integrity across extended run cycles.
- Standard 1/4-20 Thread Pattern — The 1/4-20 UNC thread pattern installs using common hand tools, making field replacement straightforward without specialized equipment.
A hex head cap screw is a structural fastener used to clamp and secure components together across a machine's frame, guards, covers, and mechanical assemblies. The thread grade — in this case Grade 8 — indicates the bolt's hardened steel construction and its ability to withstand high clamping forces and dynamic loads without yielding. On equipment like pavement saws and fireproofing pumps, which operate under sustained vibration and mechanical stress, using the correct grade fastener is critical. Installing a lower-grade substitute can lead to fastener fatigue, joint loosening, and potential component separation during operation.
