Flat Head Hexagon Socket Barrel Nuts, also known as socket barrel nuts または barrel nuts with hex sockets, are specialized fasteners designed for applications requiring a flush or low-profile connection with internal hex drive compatibility.

主な特徴

1. Flat Head Design – The top of the nut is flat (countersunk), allowing it to sit flush with or below the surface of the material, providing a smooth finish.

2. 平頭六角穴付バレルナット

3. Hexagon Socket (Internal Hex Drive) – The nut features a hexagonal recess (like a socket head cap screw) that requires an Allen key (hex key) or a hex driver bit for installation and removal.

4. Barrel Shape – The body of the nut is cylindrical (barrel-shaped), making it suitable for applications where a traditional hex nut may not fit or where rotational stability is needed.

5. Threaded Interior – Contains internal threads to mate with a corresponding bolt or threaded rod.

6. Material & Finishes – Typically made from steel (grade 8.8, 10.9, or 12.9), stainless steel (A2/A4), or brass, with optional coatings like zinc plating, black oxide, or galvanization 耐食性に優れている。

Common Uses:

• Aerospace & electronics due to their compact and secure fastening.

• DIY & woodworking projects requiring hidden or recessed nuts.

Sizing & Specifications:

• Available in metric (M3, M4, M5, M6, etc.) and imperial (1/4″, 5/16″, etc.) sizes.

• Thread pitch varies (fine or coarse threads depending on application).
