The Multiquip 8156 is a genuine OEM HHC Screw 3/8-16 x 2-1/2 designed for a wide range of Multiquip and Whiteman equipment, including JWN24, HTN27K, HTN28K, HHN31V, HHN34TVD, HTN-series ride-on power trowels, WSHE-A series vibratory screeds, BPX vibrators, and SP1G saws. As a genuine OEM component, this fastener is manufactured to the exact thread specification, length, and head geometry called out in the original equipment design. It is a direct-fit replacement that installs without modification, ensuring structural assemblies are properly secured to spec. Keep a supply on hand for scheduled maintenance, field repairs, or any rebuild where original hardware integrity matters.
Key Features
- Genuine OEM Thread Integrity — Manufactured to the exact 3/8-16 thread pitch and 2-1/2 inch length specified in Multiquip's original engineering drawings, ensuring full thread engagement and correct clamping load.
- Hex Head Cap Profile — The standard HHC hex head geometry seats flush and accepts common drive tools, making installation and torquing straightforward in the field.
- Broad Cross-Equipment Compatibility — Fits JWN24, HTN27K, HTN28K, HHN31V, HHN34TVD, HTN-series trowels, WSHE-A series screeds, BPX vibrators, and SP1G saws — a single part number that spans multiple machine families.
- Structural Fastener Confidence — Used in assemblies where correct torque and thread engagement directly affect the rigidity and alignment of working components; substituting incorrect hardware risks joint loosening under vibration.
- Torque-Critical Application Awareness — On vibrating equipment such as trowels and screeds, fastener spec compliance is essential to prevent loosening and maintain safe, consistent operation of rotating and oscillating assemblies.
A hex head cap screw is a standard structural fastener used to clamp two or more components together with controlled, measurable torque. In vibration-intensive equipment such as ride-on trowels, screeds, and backpack vibrators, fasteners are subjected to continuous dynamic loading that can work loose hardware over time if the wrong thread pitch, length, or material grade is used. The 3/8-16 designation refers to a 3/8-inch nominal diameter with a 16 threads-per-inch Unified Coarse thread, which provides strong pull-out resistance in the assemblies where this screw is specified. Using the correct OEM fastener ensures the joint behaves as the original design intended and that standard torque specifications can be applied with confidence during reassembly or maintenance.
