Boltshield Protection Caps
BoltShield® are screw-on metal caps designed to protect stud bolts and nuts from thread damage, dirt and help to prevent corrosion.
BoltShield® metal protection caps are the best bolt thread protection (BoltShield® TR Type) and bolt & nut protection (BoltShield® TD Type) for all industrial applications.
By using BoltShield® caps you will extend the life of bolts and nuts and make maintenance and repair procedures easier and faster.
They will help to reduce expensive plant downtime, thus saving money and time.
BoltShield® metal protection caps are widely used in refineries,petrochemical plants, LNG plants, offshore platforms, and steel structures.
They are commonly installed on heat exchangers, reactors and process equipment operating at temperatures up to 550°C and over, where common plastic caps would melt.
You can find BoltShield® caps to protect bolts on valves, pipelines, traffic sign posts, bridges, wind turbines and several other applications where bolts and nuts need to be protected.
Both types of BoltShield® caps are available in stainless steel (304/316), aluminium, carbon steel, zinc electroplated carbon steel and can be supplied for bolt sizes ranging from ½” to 6”, M12 to M100 (UN/metric ISO threads).
To meet all customers' needs BoltShield® caps are also available in custom-made sizes and coated upon request!
BoltShield® caps have a special internal thread, named Screw-On System, that ensures a strong and secure fixing to the bolt by matching the bolt thread (have a look at How it Works).
BoltShield® Caps are bolt protections designed to be installed manually. No extra tools are required, and they can be easily installed and removed when needed.
