LOCTITE® 248 provides the following product characteristics:

　　Technology Acrylic

　　Chemical Type Dimethacrylate ester

　　Appearance (uncured) Blue, wax consistencyLMS

　　Appearance (form) Stick

　　Fluorescence Positive under UV lightLMS

　　Components One component - requires no mixing

　　Cure Anaerobic

　　Application Threadlocking

　　Strength Medium

　　LOCTITE® 248 is a medium strength anaerobic threadlocking

　　material. It is supplied as a wax-like semi-solid, conveniently

　　packaged in a self-feeding stick applicator. As with liquid

　　anaerobic products, this material develops its cured properties

　　in the absence of air when confined between close fitting metal

　　surfaces. It achieves consistent strength and can be used on a

　　variety of metal substrates. It is particularly well suited for

　　applications where a liquid product may be too fluid to stay on

　　a part or be difficult to apply. It stores easily and allows for

　　direct contact to a threaded part during application to ensure

　　even coverage.

　　TYPICAL CURING PERFORMANCE

　　Cure Speed vs. Substrate

　　The rate of cure will depend on the substrate used. The graph

　　below shows the breakloose strength developed with time on

　　3/8 x 16 degreased steel nuts & bolts compared to different

　　materials and tested according to ISO 10964. All samples

　　pre-torqued to 5 N·m. Product applied to bolts only.
