Wacker Neuson 1000302520 Cheese Head Screw M10x40 12.9 Dacro DIN912

The Wacker Neuson is a genuine OEM Cheese Head Screw M10x40 12.9 Dacro DIN912 designed for the TH627 compact construction equipment. Sourced directly from Wacker Neuson, this fastener meets the original equipment specification used during production, ensuring a correct and consistent installation. The DIN912 standard geometry and Dacromet corrosion-resistant coating make a direct drop-in replacement with no guesswork on sizing or finish.

Key Features

• Genuine OEM Fastener Grade: — Manufactured to the 12.9 tensile class, delivering the high clamping force and torque resistance required in demanding construction equipment applications.
• Dacromet Corrosion Protection: — The Dacro coating provides superior resistance to moisture, mud, and chemical exposure — critical for hardware exposed to outdoor jobsite conditions.
• DIN912 Standard Geometry: — Conforms to DIN912 socket head cap screw dimensions, ensuring correct socket engagement and proper seating in the original threaded bore.
• Verified TH627 Fitment: — Confirmed for the Wacker Neuson TH627, matched directly to the OEM spare parts list for that machine.
• Consistent Clamp Load: — A correctly torqued, grade-correct fastener maintains joint integrity across vibration and dynamic load cycles — a worn or incorrect screw risks loosening or joint failure under operating stress.

A cheese head socket screw serves as a critical threaded fastener that clamps and secures structural or mechanical assemblies within the machine, transmitting clamping force through its threads and head bearing surface. The 12.9 grade designation means this screw is engineered for high-stress joints where a lower-grade fastener could stretch, strip, or fail under load. When a fastener of this type is replaced with an incorrect grade or finish, joint integrity and corrosion resistance are both compromised, which can lead to component loosening or accelerated corrosion in the surrounding hardware.
