How does the 17612 differ from other single-head retainers in the SMS catalog?
The 17612 uses a 3/8" stem diameter, which is larger than many standard trim retainers. This larger stem is designed for mounting holes that require a more substantial clip — such as those found on thicker bumper shield panels and certain fender liner assemblies. Using the correct stem diameter ensures a snug fit and prevents the retainer from spinning or pulling through the hole.
What applications is the 17612 typically used for?
The 17612 is used in fender liner, bumper shield, and underbody trim panel applications on a variety of domestic and import vehicles. It is particularly useful in locations where the mounting hole is larger than the standard 1/4" or 5/16" trim mounting hole, requiring the wider 3/8" stem to fill the hole properly and lock the retainer in place.
How do I know if 17612 is the right stem size for my application?
Remove the old or broken retainer and measure the mounting hole in the panel. The 17612 is designed for a 3/8" hole. If the hole is smaller (1/4" or 5/16"), choose a retainer with the correct stem size from the SMS catalog. An oversized stem will not seat correctly and can crack the surrounding panel material.
What pack size should I order?
The 17612 is available in packs of 50, 100, 200, and 300. A pack of 50 covers most single-vehicle fender or bumper liner repairs with spares. Shops that regularly stock this retainer for mixed-make service should consider the 200 or 300 pack for the best per-clip value.
Can I reuse trim retainers after removing a fender liner or bumper shield?
Trim retainers can sometimes be reused if they remain undamaged during removal, but this depends on how they were removed and whether the retention tabs are still intact. Inspect each retainer carefully before reinstalling. Any retainer with cracked, deformed, or broken tabs should be replaced with a new 17612 to ensure a secure, rattle-free fit.
