The Multiquip 1665 HHC Screw 3/8" x 16 x 2 is a genuine OEM fastener used across a wide range of Multiquip and Whiteman equipment, including WRS ride-on roller screeds, GAW180HE welders, WSHE vibratory screeds, walk-behind power trowels, and SP series saws. As a direct OEM replacement, part 1665 is manufactured to the exact thread pitch, head geometry, and material grade specified for these applications. This screw is confirmed for use on models including WRSPUDF, WRS5200, WRS5200DFPU, GAW180HE, GAW180HEA, WSHE-A Series, HDA-SERIES, JH90C, JH55C, B46, SP1G, SP2S20H, HHN34TVD, and many others in the Multiquip portfolio. Sourcing the correct OEM fastener ensures structural integrity and eliminates the risk of mismatched threading or head sizing that can damage mating components.
Key Features
- Genuine OEM Fastener Integrity — Manufactured to the exact thread specification (3/8"-16 UNC) and head dimensions called out in Multiquip's engineering documentation, ensuring correct clamp load and torque retention in the application.
- Drop-In Installation — Replaces part 1665 directly with no rework to mating holes or hardware; the hex head configuration provides standard wrench access for efficient installation and removal in the field.
- Broad Cross-Equipment Compatibility — Confirmed fitment across ride-on roller screeds (WRS, WRSPUDF, WRS5200DFPU), vibratory screeds (WSHE-A Series), gasoline welders (GAW180HE, GAW180HEA), walk-behind and ride-on trowels (HDA-SERIES, B46, HHN34TVD, JWN24HTCSL), and flat saws (SP1G, SP2S20H).
- Structural Connection Reliability — A correctly sized and properly torqued fastener maintains critical joint clamping force across vibration-intensive machines; undersized or mismatched screws can back out under load, leading to component shifting or structural failure.
- Torque and Vibration Resistance — The coarse 16 TPI thread pattern is well suited to the high-vibration operating environments common to screeds, trowels, and welders, resisting loosening over extended run cycles.
A hex head cap screw is a structural fastener used to join two or more machine components with a clamped, bolted connection. In equipment like screeds, trowels, and welders, these screws secure housings, guards, frames, and drive assemblies that must remain rigid under continuous vibration and mechanical load. When a fastener of this type fails — through thread stripping, corrosion, or incorrect sizing — the connected components can shift, creating misalignment, accelerated wear on surrounding parts, or unsafe operating conditions. Using the correct OEM-specified screw ensures the joint performs as designed throughout the machine's service life.
