MAKITA A-85531 3/4" Impact Socket 21x50 mm

MAKITA A-85531 3/4" Impact Socket Size 21x50 mm.
The Makita A-85531 socket is an essential accessory for professional tradespeople using a 3/4-inch impact wrench, especially for jobs involving stubborn or rusted nuts and bolts. Choosing an impact socket made specifically from CR-MO steel is crucial, as standard sockets cannot withstand repeated impact forces. The standard length design of 21 x 50 mm gives this socket high strength and durability while still comfortably accessing areas that do not require deep reach.

Specifications
- Maximum Durability: Made from CR-MO (Chrome-Molybdenum) steel, which offers higher impact and torque resistance than standard Chrome-Vanadium (CR-V) steel, preventing premature breakage when used with high-power impact tools.
- Efficient Torque Transmission: Engineered to minimize energy loss, allowing a 3/4-inch impact wrench to deliver maximum torque directly to the fastener.
- Long Service Life: The Black Phosphate coating resists corrosion, rust, and wear, ensuring the socket lasts longer even in environments exposed to oil or moisture.
- Operational Safety: Reduces the risk of socket failure under heavy impact, serving as a critical safety feature during operation.
Applications & Usage
- Truck & Heavy Equipment Maintenance: Ideal for removing/tightening truck wheel nuts, tractor bolts, or assembling/disassembling heavy machinery components that use 21 mm fasteners.
- Construction & Steel Framing: Suitable for fastening structural bolts on buildings, bridges, or large steel frameworks requiring robust joint integrity.
- Compatible with Heavy-Duty Impact Tools: Designed for use with 3/4-inch drive impact wrenches that deliver extremely high torque.
