With over 50 years of experience in the development and manufacture of proprietary aerospace fasteners, Monogram has developed a full scope of capabilities that provide nearly 100% internal control over our manufacturing processes. Extending well beyond our AS9100 Quality System, ISO14001 Environmental Management System and NADCAP certifications, these capabilities provide the level of schedule and quality oversight requisite in providing exceptional quality and on time delivery of the innovative cost saving solutions represented in our product offerings.


Bringing problem solving products to market is nothing new at Monogram.

  • Visu-Lok®
    Our Visu-Lok® fastener pioneered blind bolt technology and for well over a quarter century has remained an integral part of aircraft assembly. With the advent of composite aircraft structures came new fastener challenges. Again, Monogram led the way with a blind fastener design that achieved consistent high preload without the risk of composite delamination.
  • Composi-Lok®
    Today Composi-Lok® is approved on virtually all composite airframe programs throughout the world and the new Composi-Lok3, in keeping with Monogram’s commitment to a lower installed cost design philosophy, is shave free, providing the performance and reliability of our Composi-Lok with the added benefits of a flush break.
  • Radial-Lok®
    Unique in the industry is Monogram’s Radial-Lok® blind bolt. Offering 360° radial expansion throughout the fastener grip, its design properties are unmatched by any other blind bolt.

  • OSI-Bolt®
    The revolutionary OSI-Bolt® is a direct replacement for solid shank pin and collar systems. The innovative design of this high strength fastener for primary structure delivers strength with the added advantages of simple one-sided installation and a flush break-off for installed cost savings in both metal and composite structure. And now the new Ti-OSI® delivers all these advantages in a weight saving configuration.
  • Double Cylindrical Drive Nut Concept
    Our Visu-Lok®, Composi-Lok®, Radial-Lok® and OSI fastening systems are all easily adapted for robotic installation by incorporating Monogram’s ingenious Double Cylindrical Drive Nut Concept. This design significantly reduces tooling requirements while achieving additional cost savings through trouble-free installation.

Monogram remains committed to its leadership role as the premier manufacturer of innovative fasteners, delivering lower installed cost solutions to the aerospace industry and is currently developing other problem-solving solutions to meet tomorrow’s aerospace challenges.
