Wacker Neuson 5000163757 Shoulder Bolt 1/2 X 1/2

The Wacker Neuson is a genuine OEM Shoulder Bolt 1/2 X 1/2 designed for the BFS 2020AS and BFS 1318AS self-propelled walk-behind floor saws. As a direct OEM replacement, this bolt is manufactured to the exact dimensional tolerances specified by Wacker Neuson, ensuring correct seating and function within the saw assembly. Sourced directly from the manufacturer, part number delivers the same fit and performance as the original hardware it replaces. Confirm your model number before ordering to ensure compatibility with your specific machine configuration.

Key Features

• Precision-Diameter Shoulder for Controlled Clamping — The machined shoulder section provides a fixed bearing surface, maintaining accurate spacing and alignment at the fastener joint — critical for structural integrity on a working floor saw.
• Genuine OEM Hardware — Manufactured to Wacker Neuson's exact material and dimensional specifications, so thread engagement, shoulder length, and diameter match the original bolt without guesswork.
• Drop-In Replacement — Installs directly into the existing bore without reworking the mounting location, matching the thread spec and shoulder geometry of the part it replaces.
• Fits BFS 2020AS and BFS 1318AS Floor Saws — Confirmed OEM fitment for both the BFS 2020AS Saw and the BFS 1318AS Self-Propelled Walk-Behind Saw platforms.
• Maintains Structural Alignment Under Load — A worn or incorrect shoulder bolt can allow unwanted movement at the joint, leading to accelerated wear on mating components and inconsistent saw performance. The correct bolt keeps everything properly located.

A shoulder bolt differs from a standard hex bolt in that it features a precisely machined, unthreaded cylindrical section — the shoulder — between the head and the threaded portion. This shoulder acts as a pivot point, spacer, or locating pin within the assembly, controlling how components align and move relative to one another. On a floor saw like the BFS series, shoulder bolts are used where controlled clearance or rotation between parts is required, and substituting an incorrect fastener can compromise the integrity of that joint. When a shoulder bolt wears, corrodes, or is replaced with an improperly sized fastener, the result is misalignment, excess play, or premature wear in the surrounding hardware.
