Glue-in bolt

In lead climbing and sports climbing, a glue-in bolt is a type of permanent anchor used to protect climbers from falling. This bolt is characterized by being placed into a pre-drilled hole in the rock and then secured using a high-strength adhesive or epoxy. Glue-in bolts are known for their durability and strong holding power, making them ideal for long-term use and high-traffic climbing areas. They are especially favored in softer rock types where traditional expansion bolts might not hold as securely.

Examples

In lead climbing and sports climbing, a glue-in bolt is a type of anchor used to secure the climber's rope to the rock face. A climber encounters glue-in bolts predominantly on routes where extra security is necessary due to the rock type or the high frequency of use. The bolts are placed by drilling a hole into the rock and filling it with a special adhesive before inserting the bolt. The adhesive then cures, providing a robust and permanent fixture. Sports climbers often find glue-in bolts used in limestone or other softer rock formations where traditional expansion bolts might fail over time. The climber clips their quickdraw into the bolt as they ascend, ensuring safety if they fall.
