Powermax 4BA Fastener
The Powermax 4BA Screw provides a standardized fastening solution for high-precision electrical assemblies and telecommunications infrastructure. This hardware utilizes the British Association (BA) thread profile, which remains a critical standard in specialized networking frames and legacy terminal blocks. Each unit features a nominal 4.0mm diameter across the head with a 1-inch (25.4mm) shaft length. The precision-engineered threads ensure maximum surface contact within tapped holes. This design minimizes the risk of stripping during high-torque applications. The component serves as a primary mechanical link in power distribution units and equipment enclosures.
Key Features
-
Industrial Grade Material
The carbon steel construction provides the necessary tensile strength to withstand mechanical stress in rack-mounted environments. -
Corrosion Resistance
A protective zinc plating covers the entire surface to prevent oxidation in humid data center conditions. -
Thread Specifications
- Standard 4BA pitch ensures compatibility with UK-spec electrical fittings.
- The 47.5-degree thread angle provides superior grip compared to standard metric alternatives.
- Uniform thread depth facilitates rapid manual or automated installation.
Engineers specify these fasteners for environments requiring consistent clamping force. The pan head geometry distributes load across a wider area than countersunk variants. This prevents damage to thin-gauge metal panels during assembly. The 1-inch length accommodates thick busbars or multi-layered panel configurations. Consequently, this fastener remains a versatile choice for electrical contractors and network technicians. The bulk carton quantity supports large-scale deployment projects without frequent restocking delays. Each batch undergoes rigorous dimensional checks to maintain strict tolerances.

Good quality Powermax screws. The 1-inch length is exactly what I needed for the cabinet fittings. Strong metal, doesn’t bend easily even when you apply some pressure.

Hard to find 4BA fasteners in town sometimes, so I’m glad these were in stock. They work perfectly for restoring older equipment. The finish is decent and they hold tight. Delivery was also quite fast to my workshop in Industrial Area.
