• Precise Class 6g thread fit guarantees secure fastening with minimal play, reducing the risk of loosening under vibration.
• Headless, slotted drive design allows for flush mounting in tight spaces and easy installation with standard tools.
• Wide temperature tolerance from 0° to 200°F maintains structural integrity and performance across diverse operating conditions.
• Coarse 0.7mm pitch threading enables quicker installation and higher resistance to vibrational loosening compared to fine threads.
• Flat tip design provides a secure, mar-free grip on shafts and components, ideal for precision positioning.
• Full compliance with DIN 551/ISO 4766, RoHS 3, and REACH ensures adherence to international quality, safety, and environmental standards.

Professional Applications & Engineering Value

This M4 nylon set screw is engineered to address common challenges in precision assembly and sensitive environments. Its off-white nylon plastic material is inherently non-magnetic and insulating, making it perfect for electrical enclosures, medical devices, and food processing equipment where metal fasteners could cause interference or contamination. The headless, slotted drive and metric coarse thread with Class 6g fit ensure easy, tool-accessible installation and reliable holding power in shaft collars, gears, and knobs, reducing maintenance needs. With a temperature range of 0° to 200°F, it performs consistently in both indoor and moderate outdoor applications, offering a lightweight, durable alternative to metal screws without sacrificing precision.

Specification Summary & Compliance

This set screw features an M4 x 0.7mm coarse metric thread with a Class 6g tolerance for precise fit, an 8mm length, and a flat tip design.
