M4 Silicone Washer Cap (Red) 25.4mm Length | 12.7mm Flange | Silicone
Frequently specified for electrical enclosure manufacture, this high-temperature washer cap fits over M4 thread references with a 4mm internal diameter and a 12.7mm washer-style flange for consistent masking coverage. This makes it a practical red silicone flange cap for repeat masking work.
Because the cap covers both the threaded point and the washer area, it can reduce the amount of separate masking tape or masking discs needed on repetitive parts.
What Are Silicone Washer Caps?
The washer-style shoulder is designed to sit against the workpiece surface, helping to protect the contact face around a fixing. This is useful on coated assemblies where the fixing point must remain clean for later fitting, earthing or accurate reassembly.
Common Applications
- Red masking caps for repeated M4 coating jobs
- Covering pins on production fixtures
- Protecting fastener contact zones during spraying
- Masking threaded studs on assembly brackets
