Master Lock 6850 Pro Series Brass Padlock Keyed Different

Product Description

The MASTER LOCK 6850 is a Pro Series brass padlock built for demanding jobsite and facility security applications. The lock body is constructed from solid brass, providing corrosion resistance in both indoor and outdoor environments. The shackle is boron alloy steel, a hardened material that resists cutting and sawing attacks. Keyed Different (KD) configuration means each lock ships with its own unique key set, making this unit appropriate for individual-access scenarios. The 5-pin cylinder delivers increased pick resistance compared to standard 4-pin designs. Licensed trades and facilities managers rely on this lock for lockout/tagout programs, gate hasp security, and equipment access control.

This padlock is suited for residential, light commercial, and industrial use where a compact, corrosion-resistant body is required. Common applications include electrical panel lockout/tagout (LOTO) procedures, storage unit hasps, outdoor gate latches, and toolbox security. The brass body and boron alloy shackle combination makes it a practical choice in humid or marine-adjacent environments where steel bodies are prone to rust. The 2-inch body width and 1.5-inch shackle clearance accommodate most standard hasp slot sizes found on LOTO stations and padlock storage boards.

Installation Notes

Installation requires no tools — insert the shackle through the hasp or chain link and press closed until the locking mechanism engages. For lockout/tagout applications, verify compliance with OSHA 29 CFR 1910.147 control of hazardous energy standards before deploying. Always confirm the hasp or anchor point is rated for the load and security level required. Do not force a closed shackle open with tools, as this can damage the locking mechanism.
