LOCTITE® 638 is a general purpose thread locker of high bond strength. Designed for the bonding of cylindrical fitting parts, particularly where bond gaps can approach 0.25mm.
638 works not only on active metals but also on passive substrates, exhibiting robust cure performance. It offers high temperature performance and good oil tolerance, it will tolerate minor surface contaminants.
Product Benefits
High temperature resistance
High strength on all metals, including passive substrates
Tolerates minor contaminants, including industrial oils
Ideal for shafts, gears, pulleys and similar cylindrical parts
P1 NSF Reg. No.: 123000
DVGW Approval (EN 751-1): NG-5146AR0619
WRA Approval (BS 6920): 0511518
