Collection: Threaded bolts and protective caps for professional thread masking

Threads and adjacent functional surfaces need to remain usable after finishing. Threaded bolts with protective caps enable targeted thread masking during painting and coating.

Felgenprofessor offers BS and SP combinations along with EG and SG replacement components. The range includes threaded iron bolts with caps, replacement bolts and separate caps, allowing compatible components to be selected for different thread sizes.

Check thread size, component length and compatibility between bolt and cap. Use the dimensions and material information of each version as your guide. Matched components support precise masking and a structured coating process.
