The Dremec 1188X15 is a hardware component with an insulating sleeve, a hexagonal design, a diameter of M5, a length of 15mm, a spanner of 10mm, and a UL94V-2 rating. It is used for various applications that require the combination of electrical insulation and a secure fit between parts. The insulating sleeve provides electrical insulation and also some protection from abrasion and chemicals. Additionally, the hexagonal shape allows it to fit together with other components and provide a secure, non-slip fit. The M5 diameter ensures a snug fit with any other component of the same diameter. It has a spanner of 10mm which provides a larger gripping area to securely fasten the component. It also meets UL94V-2 standards, meaning it has a high flame retardance rating.
