53D897 - Walter Bolt-Out Heavy Duty Penetrating Lubricant 20L Pail

The Ultimate Rust Buster for Fabrication and Repair

Every welder and fabricator knows the frustration of a job coming to a grinding halt because of a single seized bolt or rusted pin. Whether you are repairing agricultural equipment, fixing a trailer, or retrofitting old structural steel, dealing with corrosion is part of the daily grind. Walter Bolt-Out Liquid is the heavy-duty answer to these problems. This isn't your average hardware store penetrating oil; it is an industrial-strength formula designed to cut through layers of rust, grease, and grime to free up parts that seem permanently fused together.

What makes Bolt-Out particularly good for the welding shop is its silicone-free formula. In a fabrication environment, the presence of silicone is a nightmare because it contaminates surfaces and ruins paint jobs and powder coats. With Bolt-Out, you can spray or brush it onto seized clamps, jigs, and fixtures without worrying about contaminating your workpiece or the surrounding area. It cleans up easily and leaves behind a lubricating film of microscopic Moly particles that helps prevent future rust, keeping your shop tools and the customer's equipment in better condition.

The 20L pail is the perfect size for busy shops. Instead of chasing around empty aerosol cans, you can keep a bulk supply on hand to soak heavily rusted parts or refill your own spray bottles. It works in the freezing cold of a winter morning and the high heat of a welding bay, with a temperature range up to 250 °C. This means you can apply it to parts that are still warm from torch heating (within safe limits) to help wick the fluid deep into the threads.

From loosening seized ground clamps to disassembling ancient exhaust manifolds, Walter Bolt-Out is the liquid muscle you need. It lubricates as it penetrates, protecting the threads from stripping as you apply torque. Don't let a rusted nut slow down your fabrication projects—soak it in Bolt-Out and get back to welding faster.
