Wacker Neuson 1000327772 Hex Screw 5/16"-18 UNCx1" 8.8 A2C

The Wacker Neuson is a genuine OEM Hex Screw 5/16"-18 UNCx1" 8.8 A2C designed for the TH627 indirect-fired air heater. As a direct factory-sourced fastener, matches the exact thread specification, grip length, and property class called out in the original Wacker Neuson parts list for this machine. Sourcing the correct OEM fastener means no guesswork on thread pitch or strength grade — the part goes in exactly as the manufacturer intended.

Key Features

• Correct Property Class for Structural Integrity — Grade 8.8 tensile rating matches the original design load requirement, ensuring the joint holds under the vibration and thermal cycling typical of heater operation.
• Exact Thread Specification — 5/16"-18 UNC thread form and 1" length are precisely as specified in the TH627 parts list, so the fastener seats and torques without rework.
• Genuine OEM Part — Sourced directly from Wacker Neuson, this fastener carries the same material and dimensional spec as the unit that left the factory, with no substitution in grade or coating.
• TH627 Heater Fitment Confirmed — Verified against Wacker Neuson spare parts list 418-02 for the TH627 indirect-fired air heater series.
• Prevents Joint Loosening and Component Damage — Using an undersized or incorrect-grade fastener in a heater assembly can lead to loose panels, vibration damage, or compromised enclosure seals; the correct part eliminates that risk.

A hex screw is a standard externally threaded fastener tightened with a wrench or socket tool. In equipment assemblies such as indirect-fired air heaters, hex screws are used to secure panels, brackets, mounting hardware, and mechanical components that must remain firmly located during operation. The property class designation — 8.8 in this case — indicates the fastener's minimum tensile and yield strength, which determines how much clamping force it can reliably provide. Using a fastener of the wrong strength class or thread specification can result in under-torquing, thread stripping, or joint failure over time, particularly where heat and vibration are present.
