GMS Upgrade: The Move from Phillips to Torx Screws—What Locksmiths Need to Know
In professional locksmithing, the difference between a quick job and a frustrating afternoon often comes down to the smallest components. At UHS-Hardware, we are committed to keeping you informed about the latest industry standards.
Recently, GMS (Lock Cylinders) announced a significant manufacturing transition: they are moving from traditional Phillips head screws to Torx drive screws across the majority of their product line.
This change is designed to solve a common headache in the field—stripped screw heads—while significantly improving product durability.
Why the Switch to Torx?
If you’ve ever had a Phillips driver slip and round out a screw head during a delicate cylinder installation, you know why this matters. The benefits of the new Torx drive include:
- Elimination of "Cam-Out": Torx screws are designed to prevent the screwdriver from slipping out, allowing for higher torque without damaging the head.
- Increased Durability: The six-point contact surface distributes force more evenly, extending the life of both the screw and your tools.
- Faster Installations: With a more secure fit, locksmiths can work faster and with more confidence, especially when dealing with high-volume commercial door hardware.
Implementation Schedule & Sizing Reference
The transition is already underway. Depending on current inventory levels, you will begin seeing Torx screws integrated into GMS products. To help you prep your toolbox, here is the official sizing guide provided by GMS:
| Torx Size | Product Description | Implementation Status |
| T8 | Mortise Standard / ICM, ICT, SCM | Fully Implemented |
| T6 | ICR (Interchangeable Core) | Fully Implemented |
| T15 | Rim Mounting / LFICP | Recently Implemented |
| T9 | ICM Security | Recently Implemented |
| T8 | Mortise Ext | Transition TBD (Using old stock) |
| T15 | ICS | Transition TBD (Using old stock) |
| T25 | Profile Cylinder | Transition TBD (Using old stock) |
How to Identify New Torx Inventory
GMS has made it easy to distinguish between the old and new stock without opening the box.
Keep an eye on the outside shelf pack label. New inventory featuring Torx screws will have a small Torx star symbol printed in the upper left-hand corner of the label (just above the product code). If you see that star, grab your Torx drivers instead of your Phillips!
