Heat-treated chromoly steel replacements for the soft mild-steel factory axle nuts, finished in nickel plating for corrosion resistance. The ultimate hub security upgrade for any VW with rear axles — particularly important on performance, lowered, off-road, or hard-driven cars where the factory nut is at the edge of its specification.

The factory VW nut is soft mild steel torqued to a very high spec — well over 200 ft-lbs — so installation and removal both stress the threads heavily. On hard-driven, lowered, swing-axle-to-IRS-converted, or performance cars, threads can strip on installation or the nut can deform under repeated torque cycles. The CMI chromoly version is heat-treated chromoly steel — significantly stronger than the mild-steel factory unit — and nickel-plated against corrosion around the rear hub. They install with standard tools, torque to factory spec, and last the life of the car.\u003c\/p\u003e\u003ch3\u003e\u003cb\u003eKey Features \u0026amp; Benefits\u003c\/b\u003e\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eHeat-Treated Chromoly:\u003c\/b\u003e Significantly stronger than the soft mild-steel factory nut.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eNickel-Plated:\u003c\/b\u003e Corrosion resistance in the wet, dirty environment around the rear hub.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eDirect Fit:\u003c\/b\u003e Installs with standard tools and torques to factory spec.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eSold as a Pair:\u003c\/b\u003e Left and right included.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003e\u003cb\u003eTechnical Specifications\u003c\/b\u003e\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eMaterial:\u003c\/b\u003e Heat-treated chromoly steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eFinish:\u003c\/b\u003e Nickel plated\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eSold As:\u003c\/b\u003e Pair (left + right)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eManufacturer:\u003c\/b\u003e CMI\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003ePart Number:\u003c\/b\u003e #A13-CMI\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003e\u003cb\u003eFrequently Asked Questions\u003c\/b\u003e\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eWhat's the torque spec?\u003c\/b\u003e The factory VW rear axle nut torque spec is approximately 217 ft-lbs (294 Nm) — verify against your specific service manual. This is a very high torque value and requires a long breaker bar or torque multiplier. Too loose and the hub walks, too tight and you stress the threads.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eDo I need a new cotter pin?\u003c\/b\u003e The VW rear axle nut is a castle-style nut secured with a cotter pin through the axle. Always use a new cotter pin on installation; never reuse an old one.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eWill these work on my swing axle Beetle?\u003c\/b\u003e Yes. Swing axle rear axle nuts use the same general thread spec as IRS axles on Type 1 cars.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eAre they worth it on a stock daily driver?\u003c\/b\u003e For a stock, gently-driven Beetle the factory nut is generally adequate if installed correctly. The chromoly version is cheap insurance and the right choice if you'll remove\/reinstall axles multiple times or run performance modifications that increase rear-end loads.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eWhat happens if I run a worn or damaged factory nut?\u003c\/b\u003e Best case, slow loosening leading to a wobbly rear wheel; worst case, sudden thread failure and rear wheel separation at speed. The axle nut is one of those fasteners where \"good enough\" isn't good enough.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eDo they include washers?\u003c\/b\u003e No — the axle nuts only. The factory VW axle washer should be in good condition or replaced with a known-good unit if bent or distorted.\u003c\/li\u003e\n\u003c\/ul\u003e\u003chr\u003e\u003ch3\u003e\u003cb\u003eExplore Related Categories\u003c\/b\u003e\u003c\/h3\u003e\u003cp\u003eBrowse more from our catalog: \u003ca href=\"\/collections\/axles\"\u003eAxles\u003c\/a\u003e, \u003ca href=\"\/collections\/suspension\"\u003eSuspension\u003c\/a\u003e, and \u003ca href=\"\/collections\/all-vw-aircooled\"\u003eAll VW Air-Cooled\u003c\/a\u003e.\u003c\/p\u003e","brand":"CMI","offers":[{"title":"Default Title","offer_id":44318235492467,"sku":"A13-CMI","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0278\/2760\/1523\/files\/20260203_182209.jpg?v=1771405353","url":"https:\/\/www.washburnsmetal.com\/products\/chromoly-nickel-plated-vw-axle-nuts-pair-the-ultimate-security","provider":"Washburn's Metal","version":"1.0","type":"link"}
