Wacker Neuson 5000116452 Screw 3/8-16 X 2-1/2 Hx.Hd.

The Wacker Neuson Screw 3/8-16 X 2-1/2 Hx.Hd. is a genuine OEM fastener designed for the HP, HPG, HC, HE, SC, SE, and SP vibratory truss screed series. As a direct OEM part sourced through authorized Wacker Neuson supply channels, is manufactured to the exact thread specification, grip length, and head geometry required for its application across these screed families. This screw fits a wide range of power sections and modular screed sections, including HPG100A, HPG50A, HP100A, HP50A, HC25, HC50, HC100, HE25, HE50, HE100, SP50, SP75, SC25, SC50, SC75, SE25, SE50, and SE75 configurations. Keeping the correct hardware on hand means your screed sections assemble cleanly and hold securely, maintaining the structural integrity of the unit across every pour.

Key Features

• Correct Thread and Length Specification — 3/8-16 thread with a 2-1/2 inch grip length ensures proper clamping engagement in screed section mounting applications without over- or under-penetration.
• Genuine OEM Quality — Manufactured to Wacker Neuson's original material and dimensional standards, delivering consistent torque retention and resistance to loosening under vibration.
• Broad Screed Series Compatibility — Fits HP, HPG, HC, HE, SC, SE, and SP vibratory truss screed power sections and modular sections, covering a wide range of Wacker Neuson concrete finishing equipment.
• Vibration-Resistant Fastening — Truss screeds operate under continuous vibration; correct fastener spec helps prevent joint loosening that could affect screed levelness and surface finish quality.
• Drop-In Replacement — Hex head drive pattern and standard UNC threading match the original hardware, allowing straightforward installation with common hand tools.

A hex head screw may seem like a simple component, but in a vibratory truss screed, every fastener in the structural assembly is working against constant mechanical vibration during operation. The 3/8-16 X 2-1/2 Hx.Hd. screw is used to secure screed sections and power section components together, maintaining the alignment and rigidity that allow the screed to produce a flat, consistent concrete surface. When fasteners stretch, strip, or go missing, screed sections can shift or develop play, compromising surface levelness and potentially damaging the screed frame itself. Using the correct OEM replacement screw — with the right thread engagement and head bearing area — keeps the assembly tight and performing as intended.
