Load Monitoring Fastener+® (LMF+®) is a wireless, accurate, and automatic load monitoring fastener system. The LMF+® is extremely easy to use and will allow users to continually observe and record the true tension (tightness) of fasteners, both during installation and while equipment is in operation. Automated alerts will notify you if tension exceeds or falls below predetermined and updateable values or thresholds.

Loose Bolts Break. It’s a simple truth, but one that has caused countless failures, unplanned downtime, and massive repair costs in industries just like yours. Every day, bolted joints in critical applications quietly lose tension—until they fail. The consequences? Catastrophic equipment damage, production delays, and unexpected safety hazards.

Torque Does Not Equal Tension. You tighten bolts to a specified torque, but that doesn’t guarantee they’re holding the load they should. Friction, surface conditions, and operator variability mean that torque can give a false sense of security. The result? Bolts that are either too loose or overstressed—both lead to failure.

Ensure Every Installation is Correct. BoltSense® LMF+®  doesn’t guess. It measures. Our tension-monitoring fasteners confirm that each bolt is correctly loaded from the start and stays that way during operation. This isn’t about selling you more bolts, it’s about giving you confidence that your equipment is secure, your downtime is minimized, and your team is safe.

Load Indicating Fastener includes the same base fastener as the LMF+® product, but without the continuous transmitting cap. Instead, the LIF has a stainless steel dust cap, and readings can be taken anytime with a clip-on reader (both magnetic and screw-on.)
