Class 8 Nylon Insert Nuts P Type- M12 (Bag of 8)

Class 8 Nylon Insert Nuts P Type – M12 (Bag of 8) are high-strength, vibration-resistant locking nuts manufactured from carbon steel with a bright zinc plated (BZP) finish. Conforming to DIN 982, these M12 nyloc nuts feature a nylon insert that deforms over the mating bolt thread, creating a secure prevailing-torque lock that prevents loosening under vibration and dynamic loads. Supplied in a convenient bag of 8, they suit both trade professionals and DIY users working with M12 fixings.

Key Features and Specifications

• Standard: DIN 982 (also meets ISO 7040)
• Grade / Class: Class 8 (Grade 8) carbon steel
• Type: P-Type (high-type) — taller body than T-Type for greater thread engagement

• Width across flats (A/F): 19mm — fits standard 19mm spanner or socket
• Total height: 14mm
• Finish: Bright Zinc Plated (BZP) for corrosion resistance in dry and low-humidity environments
• Insert material: Nylon — grips thread on tightening; nut can be re-used, though locking performance reduces with repeated removal
• Pack quantity: 8 nuts per bag
• Temperature rating: Suitable up to approximately 120 °C (nylon insert limits use in high-heat applications)

Applications

• Structural steelwork and steel frame construction
• General construction bolted connections requiring vibration resistance
• Machinery assembly, plant maintenance, and agricultural equipment
• Automotive and trailer fabrication
• Securing threaded rod (studding) and hex bolts in building and civil engineering
• Garden machinery, gates, and fencing hardware

Why Choose This Product

The P-Type design provides a taller nut body than the T-Type equivalent, giving deeper thread engagement and a more robust lock — preferred by trade users where bolt-load security is critical. The Class 8 BZP steel construction delivers the strength needed for structural and mechanical applications, while the zinc plate finish guards against corrosion in typical indoor and sheltered outdoor environments. Sold in a bag of 8, this format is ideal for small jobs, repairs, and topping up site supplies without over-ordering.
