Product Description
M52 x 87mm - Self Threading Stud Caps - Black - LDPE | Vital Parts - STSC-M52-87-B
Our Self Threading Stud Caps are designed to protect, conceal, and secure exposed threaded studs or bolts in a wide range of industrial environments. These caps provide a simple yet highly effective solution for improving safety and prolonging the life of fasteners, especially in outdoor and corrosive settings.
What are Self Threading Stud Caps?
Self Threading Stud Caps, also known as Thread Caps or Stud Protection Caps, are durable covers made from high-quality LDPE (Low-Density Polyethylene). These caps screw directly onto external threads, forming a secure fit that resists accidental removal. Their internal ribs cut into the threads as the cap is applied, creating a tight connection that seals out dirt, moisture, and other contaminants.
Key Features:
- Manufactured from premium LDPE for flexibility and resilience
- Self-threading design with internal ribs for a secure, tamper-resistant fit
- External fins enhance grip for easy manual installation
- Temperature resistance up to 70ºC
- Chemical resistance to seawater, oils, greases, fuels, alcohols, and non-oxidising acids and alkalis
- Available in standard black or custom RAL colours upon request
- Size range from M16 to M90, with multiple length options
- Compatible with our full range of snap-fit and dome-style protection caps
