✓ In stock Long 1/4" diameter window regulator rivet for GM, Ford, and Chrysler vehicles. This aluminum-body, steel-mandrel rivet handles the thicker panel stack found in window regulator mounting locations where a long grip range (33/64"–19/32") is required. Shares the same 1/4" diameter and 1/2" flange as the short version, but is sized for deeper panel assemblies.

The short rivet (16837) has a grip range of 1/32"–9/64", designed for thin regulator bracket stacks. The long rivet (16838) has a grip range of 33/64"–19/32", designed for thicker panel assemblies. Both share the same 1/4" diameter and 1/2" flange. Measure your total panel thickness to select the correct version. Why does the long rivet have such a specific grip range? Window regulator bracket mounting depths vary by vehicle model and door configuration. The long rivet's 33/64"–19/32" grip range targets the deeper stack assemblies found in some GM, Ford, and Chrysler doors. Using a rivet outside its grip range results in an under-set or over-set condition that weakens the joint. How do I replace a window regulator rivet? Drill out the old rivet using a drill bit sized to the rivet diameter (1/4" / 6.4mm). Clean the hole of any burrs, align the regulator bracket, and install the new rivet using a standard rivet gun. The mandrel will pop when the rivet is fully set. Can I use this rivet for non-window-regulator applications? The 1/4" diameter and large 1/2" flange make this rivet suitable for other heavy-duty body panel fastening where panel stack thickness falls in the 33/64"–19/32" range. Verify hole diameter and grip range match your application before ordering. What pack sizes are available? Available in packs of 50, 100, 200, and 300 to cover single-window repairs or bulk shop supply needs.
