Lock-Out by Tanner
Lock-Out® screws offer a significant step up from standard tamper-resistant fasteners, featuring a patented oval center pin drive and high torque resistance. The smooth, button-head profile is also a good deterrent against gripping tools like locking pliers. However, the limited number of unique drive patterns may reduce their effectiveness in high-risk applications or against targeted threats.

Ultra-Lok II by Loss Prevention Fasteners
The Ultra-Lok II® features a proprietary keyway with a robust center stud, adding strong protection against tampering with standard tools. Tools are restricted and require authorization to purchase, increasing control—but not eliminating the possibility of eventual tool access. The button head design also limits grip area for pliers, especially when paired with proper torque. Minimum order quantities may limit use for small projects, but this fastener offers solid mid-tier security where distribution control is important.
