Description
The Wheeler FAT Stix Torque Limiter takes the fuss out of tightening screws to spec. This one is preset to 50 in-lb, so there's no dial to fumble with and no chance of accidentally cranking past the mark. Once it reaches the set value, it slips, letting you know the fastener is right where it needs to be. That makes it a favorite for anyone mounting scopes, snugging action screws, or working on higher-torque fasteners where over-tightening can crush a ring or strip a threaded hole.
Why the 50 in-lb FAT Stix Earns a Spot in Your Kit
Accuracy is where these limiters shine. Each FAT Stix is rated within plus or minus 5 percent of its stamped value, which is plenty tight for repeatable gun work. The 50 in-lb version lands on the heavier end of the range, making it a good match for barrel-related fasteners, bases, and other parts that call for a firmer hold than your typical scope ring cap screw. Because the torque is factory-set, you get the same result every single time without hunting for the right setting.
Built to Take Regular Bench Use
Wheeler builds the FAT Stix from S2 tool steel hardened to the mid-50s on the Rockwell C scale, so this is not a throwaway gadget. It shrugs off repeated use at the bench or the range and keeps its calibration far longer than cheaper preset tools. The compact size means it tucks into a range bag or tool roll without taking up real estate.
Works With Gear You Already Have
The limiter uses a universal design that fits the Wheeler FAT Stix T-Handle Driver or basically any driver that accepts standard 1/4" bits. That flexibility lets you build out a set of different torque values over time and swap them onto a single handle. For a DIY armorer or a hobbyist wrenching on more than just firearms, that kind of versatility goes a long way.

Frequently Asked Questions
Does the FAT Stix Torque Limiter come with a handle or driver?
No, this is the individual 50 in-lb limiter sold on its own. It's designed to attach to the Wheeler FAT Stix T-Handle Driver or any driver that accepts standard 1/4" bits. If you already own a compatible driver, you're set. If not, you'll want to pick one up alongside it.
How accurate is the 50 in-lb setting?
Wheeler rates the FAT Stix within plus or minus 5 percent of the stamped torque value. For scope mounting, action screws, and general gun work, that's a reliable margin. Since the value is factory-preset, you get the same result on every fastener with no dialing required.
What kind of jobs is a 50 in-lb limiter good for?
The 50 in-lb value sits on the heavier end of the FAT Stix lineup, so it suits firmer fasteners like certain bases, mounts, and barrel-related hardware. Lighter jobs like ring cap screws usually call for a lower value. Many folks build out several limiters to cover the full range of what they work on.
Is the FAT Stix limiter durable enough for regular use?
Yes. It's machined from S2 tool steel and hardened to the mid-50s on the Rockwell C scale, so it holds up to repeated bench and range use. It's a tool built to keep its calibration over the long haul rather than a disposable gadget.
