Wacker Neuson 5000116752 Shoulder Socket Screw 1/2X3/4X1-3/8

The Wacker Neuson is a genuine OEM Shoulder Socket Screw 1/2X3/4X1-3/8 designed for the CRT48 and CRT60 series ride-on concrete power trowels. Sourced directly from Wacker Neuson, this screw meets the exact dimensional and material specifications required for proper assembly and torque retention in your machine. It is confirmed to fit a wide range of CRT48 and CRT60 models, including the CRT48-31V, CRT48-33K, CRT48-34V, CRT48-35L, CRT48-35V, CRT48-37V, CRT48-57K, CRT60-66K, CRT60-74L, and CRT60-74LX. When you need an exact replacement, this genuine part eliminates the guesswork of sourcing a compatible alternative.

Key Features

• Genuine OEM Dimensional Accuracy — Machined to the exact shoulder diameter, thread pitch, and overall length specified for this fastener position, ensuring correct clamping load and seating depth on assembly.
• Socket Drive Configuration — Hex socket head allows precise torque application with a standard hex key, even in the tight clearances common on CRT trowel assemblies.
• Broad CRT48 and CRT60 Coverage — Fits across multiple CRT48 variants — including V, L, K, and PS configurations — as well as CRT60-66K, CRT60-74L, and CRT60-74LX models.
• Shoulder Design for Precision Alignment — The unthreaded shoulder section locates and aligns mating components accurately, maintaining consistent geometry at the fastener joint throughout the machine's service life.
• Structural Integrity at the Joint — A worn, stripped, or incorrect screw in this position can allow component movement, vibration-induced loosening, or misalignment — all of which affect trowel performance and surface finish quality on finished concrete.

A shoulder socket screw combines a precision-ground unthreaded shank with a threaded end to serve a dual purpose: the shoulder locates and aligns two mating components while the threaded portion draws them together and holds them in place. Unlike a standard fastener, the shoulder itself bears the lateral load at the joint, making correct sizing critical. On a ride-on concrete trowel like the CRT48 or CRT60, fasteners in this category are used where precise component positioning must be maintained under continuous vibration and operational stress. Using an incorrectly dimensioned screw can introduce play at the joint, leading to accelerated wear of surrounding components and inconsistent trowel blade geometry.
