Powermax 4BA Screw
The Powermax 4BA Electrical Screw delivers a reliable mechanical interface for mounting electrical accessories to standard containment boxes. These fasteners adhere to the British Association thread profile, ensuring seamless integration with existing infrastructure in commercial or industrial settings. The extended 2-inch shaft length addresses specific installation challenges where the mounting box resides deep within the wall structure.
Key Features
-
Thread Precision
Each unit maintains a strict 0.66mm pitch to prevent cross-threading during high-volume manual installation. -
Material Composition
- High-grade carbon steel construction ensures the fastener resists torque-induced deformation.
- A protective zinc coating provides a barrier against environmental moisture and oxidation.
-
Head Geometry
The standardized slotted pan head allows for manual adjustment using common flat-head drivers for precise torque control. -
Load Distribution
The wide head profile distributes mechanical pressure evenly across the accessory faceplate surface to prevent cracking.
Installers often face alignment issues when wall finishes exceed standard depths. These Powermax fasteners provide a solution for deep-set mounting requirements in modern office builds. The 4BA specification remains the standard for electrical accessory mounting in many regions. Using standardized hardware prevents damage to the threaded lugs of the backbox. The high-tensile steel allows for firm tightening without stripping the screw head. This reliability is crucial for maintaining the safety and aesthetics of electrical installations. Procurement teams benefit from the bulk carton size of 50 pieces. This packaging reduces the frequency of reordering for large-scale infrastructure projects. The zinc plating ensures longevity even in environments with high humidity levels. These components withstand significant shear forces during the mounting of heavy-duty metal faceplates. The precision-engineered threads ensure a consistent fit across all batches. This consistency minimizes downtime caused by stripped threads or incompatible hardware during site deployment. Site managers can rely on the uniform quality of these fasteners to maintain project timelines. The screws provide a secure grip that resists loosening due to building vibrations or temperature fluctuations. This makes them suitable for data center environments where equipment stability is paramount.

Good quality screws. The threading is clean and they fit perfectly into the conduit boxes without stripping.
Sarah Atieno (verified owner) –
These 2-inch screws are exactly what I needed for the deeper socket boxes we installed at the office. The 50-pack is also better value than buying small packets at the local hardware. Delivery was fast to Westlands.

Finding long 4BA screws can be a headache sometimes in town, but these Powermax ones are solid. Used them for mounting switch plates on a thick tiled wall. They don’t bend easily even when you apply some pressure. Only wish they had a 100-pack option for bigger sites, but the 50-pack works for now.
