Wacker Neuson 5100067277 M10 x 30 Allen Cap Screw

The Wacker Neuson M10 x 30 Allen Cap Screw is a genuine OEM fastener designed for the Hydraulic Thumb (3–4 Ton) series. Sourced directly from Wacker Neuson, this screw meets the exact material and dimensional standards set for the original assembly, ensuring a correct and secure fit every time. If you are servicing or reassembling a Hydraulic Thumb attachment, using the correct OEM fastener is the straightforward way to restore the connection to its original specification.

Key Features

• Genuine OEM Fastener Grade — Manufactured to the precise tensile and thread specification required for structural fastening on hydraulic attachment hardware, so the joint holds under load without backing out or stripping.
• M10 x 30 Allen Drive Profile — The hex socket (Allen) head allows controlled torque application in tight mounting locations typical of thumb bracket assemblies, reducing the risk of cam-out during installation.
• Direct Replacement for Hydraulic Thumb (3–4 Ton) — Part 5100067277 is the factory-specified screw for the Wacker Neuson Hydraulic Thumb in the 3–4 ton class, confirming compatibility before you order.
• Structural Integrity of the Thumb Pivot — A correctly torqued cap screw keeps the thumb bracket securely anchored to the excavator arm; a worn, stretched, or incorrect fastener can cause play in the pivot, affecting grip precision and cycle repeatability.
• Single-Part Simplicity — Stocking the correct individual fastener by OEM part number means a quick, targeted repair without replacing larger sub-assemblies or sourcing generic hardware that may not match thread pitch or head geometry.

An Allen cap screw — also known as a socket head cap screw — is a threaded fastener with a cylindrical head and an internal hex drive socket. In hydraulic attachment assemblies such as an excavator thumb, these screws are used to clamp bracket components, pivot plates, and structural members together under precise torque. Because they transmit both clamping force and shear loads, using the correct grade and size is important; an undersized or lower-grade substitute can fatigue, loosen, or shear under the cyclic stress of digging and gripping operations, leading to unwanted movement or component damage.
