Sealing Screws for Tamper-Evident Applications

Cal Fasteners offers sealing screws designed to provide secure, tamper-proof fastening in critical applications. Made from durable, high-quality steel with a corrosion-resistant zinc finish, these screws feature holes drilled through the shank or hex head—allowing a wire or cable to be threaded through for visible tamper detection.

Product Highlights:

  • Tamper-Evident Security: Holes drilled through the screw shank or hex head allow for use with sealing wire or cable.

  • Durable Steel Construction: Built to withstand demanding environments; zinc plating provides added corrosion resistance.

  • Available in Standard Sizes: Multiple sizes in stock and ready to ship.

  • Custom Materials Available: Stainless steel and select other materials available upon request.

For maximum effectiveness, use in combination with our sealing wing nuts.

Common Uses:

  • Electrical enclosures
