The Multiquip 1550163320 is a genuine OEM Through Bolt designed for BLW-400SSW welders and KD1800, KD1800KD6, and KD6 core drills. As a direct OEM replacement, this through bolt is sourced from Multiquip to match the original component specification, ensuring correct installation without modification. Whether you are servicing a welder or a core drill from the KD series, this is the verified part for the job.
Key Features
- Genuine OEM Construction — Manufactured to the same material and dimensional standards as the original, maintaining structural integrity under the clamping loads and vibration typical of welding and core drilling equipment.
- Direct Drop-In Replacement — Threads and length match the original mounting points on BLW-400SSW and KD series equipment, so installation is straightforward with standard tooling.
- Broad KD Series Fitment — Confirmed compatibility with KD1800, KD1800KD6, and KD6 core drills, as well as the BLW-400SSW welder, covering multiple machines with a single part.
- Maintains Clamping Integrity — A through bolt is a primary structural fastener; using a correctly rated replacement keeps assemblies securely torqued and prevents component shift or looseness during operation.
A through bolt is a full-length fastener that passes completely through a housing, frame section, or stacked assembly to clamp components together with a nut on the opposite end. Unlike a standard stud or screw that threads into one surface, a through bolt distributes clamping force across the full depth of the assembly, which is critical in high-vibration equipment such as core drills and welders. When a through bolt stretches, strips, or fails, the assembly it secures can shift or come apart, leading to misalignment, accelerated wear on surrounding components, or unsafe operating conditions. Replacing a worn or damaged through bolt promptly with the correct OEM part restores the original clamping load and keeps the machine operating as designed.
