Cross Slot 桶狀螺帽 are specialized fasteners designed for applications requiring secure, adjustable, and tool-free connections. Here’s a detailed description:

功能與設計：

1. Barrel-Shaped Body – Cylindrical form allows rotation within a pre-drilled hole, enabling multi-directional adjustment.

2. Cross Slot Mechanism – The top features a cross-shaped slot (two perpendicular grooves) that accepts a compatible flathead screwdriver or a cross-slot key for installation/removal.

3. 螺紋內部 – Contains internal threads to mate with a machine screw or bolt, creating a strong clamping force when tightened.

4. Flanged or Non-Flanged – Some versions include an external flange to distribute load and prevent pull-through in softer materials.

5. Material Options - 通常由 鋼、不銹鋼或黃銅 耐腐蝕性和耐用性。

優勢：

• Tool-Free Adjustment – The cross slot allows quick tightening/loosening without specialized tools (ideal for field adjustments).

• 360° Rotation – The barrel design lets the nut pivot, accommodating misaligned holes or angular adjustments.

• Secure Grip – Threads resist loosening under vibration (common in automotive, furniture, or machinery).

• 低調 – Sits flush or semi-flush when installed, saving space.

常見應用：

• 家具組裝 – Used in flat-pack furniture for easy, tool-free tightening.

• Automotive & Aerospace – Securing panels or components requiring frequent access.

• 工業設備 – Adjustable mounts or fixtures.

• Consumer Electronics – Internal fastening in devices needing serviceability.

安裝：

1. Insert the barrel nut into a pre-drilled hole (often with a shoulder or lip to retain it).

2. Align the cross slot for screwdriver access.

3. Drive the mating screw through the opposing part and into the barrel nut’s threads, tightening as needed.
