Wondering whether to replace the thumb handle or the hex screw on your Quad Lock 360 Dual Pivot Arm? This comparison explains the difference and helps you decide.

Quick answer

Choose the replacement thumb handle and hex screw kit if your pivot arm's handle is worn, cracked, or missing. If the handle is fine but the screw is stripped or damaged, you can often replace just the screw—but the kit is the most straightforward way to restore your Quad Lock 360 Dual Pivot Arm.

Understanding the parts

The Quad Lock 360 Dual Pivot Arm uses a thumb handle and a hex screw to lock the arm in place. The handle is the part you grip to tighten or loosen the arm, while the hex screw is what actually secures the handle to the arm. Over time, either part can wear out from frequent adjustments or accidental drops.

The replacement kit includes both the thumb handle and the hex screw, so you can address either issue in one purchase. If you only need the screw, the kit still covers you—but you may prefer to buy just the screw if it's available separately. However, the kit is a practical choice because it ensures you have both parts on hand.

Trade-offs: handle vs. screw replacement

Replace the handle: If the thumb handle is cracked, stripped, or uncomfortable to grip, replacing it restores the pivot arm's usability. The kit includes both the handle and the screw, so you get a complete fix. Inspect the handle for cracks or wear before deciding.
Replace the hex screw: If the handle is fine but the screw is stripped or damaged, you can replace just the screw. The kit provides the screw, but buying the full kit means you also have a spare handle for future needs. If you only need the screw, check if it's available separately to save money.
Buy the kit: The replacement kit is the simplest option because it covers both parts. It's a genuine Quad Lock part, so it maintains compatibility with the 360 mounting system. If you're unsure which part is worn, the kit is a safe choice.
