The Wacker Neuson is a genuine OEM Hexagonal Head Cap Screw designed for the BFS walk-behind floor saw series and the APT trailer-mounted pump series. As a direct OEM replacement, this fastener is manufactured to the exact dimensional and material specifications required by Wacker Neuson, ensuring correct torque retention and a secure, rattle-free joint. It fits a wide range of APT configurations — including the APT4T, APT6T, APT8T, and APT8S in both standard and Cold Weather variants — as well as the BFS 2020AS and BFS 1318AS floor saws. Keeping the correct fastener in place is essential wherever structural or mechanical assemblies are joined under load or vibration.
Key Features
- Genuine OEM Fastener Grade — Manufactured to Wacker Neuson's exact material and tensile specifications, so thread engagement and clamping force meet the original design intent of the assembly.
- Hexagonal Drive for Positive Wrench Engagement — The hex-head profile accepts standard wrenches and sockets for consistent torque application without fastener rounding or cam-out.
- Wide Fitment Across Two Equipment Families — Confirmed for the BFS 2020AS and BFS 1318AS walk-behind floor saws and the full APT4T, APT6T, APT8T, and APT8S pump lineup, including Surge Brake, Electric Brake, and Cold Weather configurations.
- Maintains Joint Integrity Under Vibration — Correctly spec'd fasteners resist loosening in high-vibration environments typical of saw and pump operation, protecting surrounding components from wear caused by loose hardware.
- Direct OEM Part Number Cross-Reference — Part number 5000163774 matches Wacker Neuson's own parts catalog, eliminating guesswork when ordering for scheduled maintenance or field repairs.
A hexagonal head cap screw is a threaded fastener used to clamp and secure mechanical assemblies — joining housings, brackets, guards, and structural components together with controlled clamping force. In equipment like floor saws and trailer pumps, fasteners at critical joints are subject to continuous vibration, load cycling, and environmental exposure; using the correct grade and dimensional specification ensures the joint holds its clamping load over time. When a fastener is the wrong spec, under-torqued, or worn, it can allow movement between mating parts, leading to accelerated wear, misalignment, or component damage that extends well beyond the fastener itself.
