Frequently Asked Questions About International PayStar 5000 Frame Nut Covers

What are the thread sizes and types that these frame nut covers fit?

Our International PayStar 5000 frame nut covers are designed to fit standard 33mm hex nuts commonly found on PayStar 5000 frames. They accommodate both metric M22 and M24 thread sizes with 1.5 and 2.0 thread pitches. Before ordering, we recommend verifying your specific nut size by measuring across the flats of your frame nuts with a caliper or checking your truck's specification sheet.

Will these covers fit my specific PayStar 5000 model year?

These frame nut covers are compatible with International PayStar 5000 models from 2012 through 2018. While the frame design remained consistent across these years, some specialty configurations like SFA (Set Forward Axle) models may have different nut spacing. For 2019 and newer models, International made slight changes to the frame rail specifications that may affect fitment. Contact our support team with your VIN if you need verification for your specific truck.

How do these covers stay secured during heavy-duty use and highway speeds?

Each cover features a push-on design with internal retention tabs that grip the nut securely. The ABS plastic construction includes UV stabilizers to prevent cracking and maintain flexibility in extreme temperatures from -40F to 180F. Many drivers report these covers staying firmly in place even after months of severe-duty applications like logging and construction work. For added security in extreme conditions, a small dab of silicone adhesive can be applied inside the cover during installation.

What finishes are available and how do they hold up to road chemicals and weather?

We offer these covers in chrome-plated ABS, polished stainless steel look, and matte black finishes. The chrome-plated versions feature a triple-layer chrome process that resists corrosion from road salt and chemicals. The stainless steel look option uses a specialized metallic coating that maintains its appearance without the weight of actual stainless. The matte black finish includes a textured surface that hides minor scratches and maintains its appearance even after extended exposure to diesel fuel and hydraulic fluid.

How many covers do I need for a complete installation?

A standard PayStar 5000 typically requires 40-48 frame nut covers for complete coverage, depending on your wheelbase and equipment configuration. Single-axle models generally need 40 covers, while tandem-axle setups require 44-48. This includes all visible frame rail nuts, suspension mounting points, and crossmember connections. We recommend ordering 2-4 extra covers as spares, as they can occasionally be lost during tire changes or maintenance work.
