Public infrastructure—meticulously designed by engineers who dedicate years to optimizing safety, efficiency, and durability—too often becomes the target of senseless vandalism and tampering and theft. These structures, which include bridges, power grids, transit systems, and public parks, form the backbone of modern society; yet, they face alarming rates of damage. Studies indicate that metal theft alone, particularly copper wiring from power lines and railway systems, costs the U.S. economy over $1 billion annually. Cities report that 5-20% of telecommunications infrastructure is directly affected by theft and sabotage.

Rolf Scholtz, and Peter Scholtz, founded Spinguard on March 20, 2025, in Minneapolis, Minnesota. The idea first emerged in 2020 when they realized that no effective tamper-proof bolt options existed. Existing solutions were either too generic and easy to defeat, breakaway designs that rendered bolts unusable, or highly secure but permanent. Determined to solve this problem, they developed a cost-efficient bolt cover that fits onto existing hex bolts while offering unbeatable security. Their relentless innovation led to the creation of Spinguard—the tamper-proof bolt cover that transforms any standard hex bolt into a secure, tamper proof fixture.
