The Master Lock S31 Zenex Safety Padlock is specifically designed for Lockout/Tagout (LOTO) procedures where compliance, identification, and controlled access are essential. Each padlock is supplied with the standard Danger - Locked Out - Do Not Remove warning, clearly printed on the front.

Made from Master Lock's advanced Zenex thermoplastic compound, the body is lightweight yet impact-resistant, non-conductive, and highly resistant to chemicals, solvents, UV exposure, and extreme temperatures. With an operating temperature range of -70 °F to +350 °F, it is ideal for demanding industrial environments.

The key-retaining design prevents the key from being removed when the padlock is open, preventing accidental re-energisation and ensuring proper LOTO discipline. Keyed-different versions use Master Lock's high-security 6-pin cylinder with 100,000+ possible pin configurations, minimising the chance that another worker's key will operate the wrong lock.

Each padlock includes a set of multilingual identification labels, allowing clear worker, department, or task labelling straight out of the box.

Keys

  • Supplied with 1 key per padlock (standard safety practice one worker, one key).

  • Available keyed alike or keyed different, depending on operational needs.

Uses & Applications

Ideal for:

  • Electrical lockout

  • Machinery isolation

  • Valve lockout

  • Multi-worker LOTO procedures

  • Chemical, industrial, warehousing, and engineering environments

  • Any application where non-conductive, identifiable safety locks are required
