Are You Matching Your Fastener Angles? Here’s Why It Matters

One of the most common mistakes in fastening is using the wrong bevel angle on your washer. A countersunk washer with a 90° taper won’t seat correctly with a 100° screw. That slight mismatch might seem harmless, but over time, it causes uneven force distribution, which leads to loosening, vibration, and potential material damage.

The solution is simple: Always check the screw head angle before selecting your precision countersunk washer. Whether it’s 82°, 90°, or 100°, a correct match means better seating, stronger fastening, and longer product life. This is especially important in mission-critical industries like aerospace and automotive, where every fastener must perform at 100%.
