Detailed Engineering Specifications

A high-performance industrial component, this M19 Nylon Hex Head Cap Screw features a nominal diameter of 19mm with a thread pitch of 1.5mm (standard for M19). The overall length is precisely 15mm. The hex head has a width across flats of 21mm, ensuring compatibility with standard M19 tools. Constructed from durable, high-density Nylon 6/6, it exhibits exceptional resistance to a broad spectrum of chemicals, solvents, and moisture, making it suitable for corrosive atmospheres. Its inherent non-conductive nature provides excellent electrical insulation, crucial for electronic assemblies and applications where static discharge is a concern. The material's lightweight profile contributes to reduced overall assembly weight without compromising mechanical integrity for its intended load-bearing capabilities.

Installation Procedure

1. Ensure the mating tapped hole or nut is clean and free of debris. 2. Thread the Nylon Hex Head Cap Screw by hand to confirm proper engagement and avoid cross-threading. 3. Tighten the screw to the recommended torque using an appropriate hex driver or wrench, being mindful of Nylon's lower yield strength compared to metals to prevent over-tightening.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the Nylon screw, leading to thread stripping or head deformation.Refer to torque specifications for Nylon fasteners and use a torque wrench. Avoid excessive force, especially in soft materials.
Using metal tools with sharp edges that can damage the Nylon head.Employ tools with smooth, rounded edges, or consider using impact-resistant tool sockets designed for plastic fasteners.

Common Applications

  • Chemical Processing Equipment
  • Electrical and Electronic Assemblies
  • Medical Device Manufacturing

⚠️ Engineering Warnings

  • Not suitable for high-stress structural applications or environments exceeding Nylon's operational temperature range.
  • May degrade under prolonged exposure to UV radiation; consider UV-stabilized variants for outdoor use.
