S-92098A133 M4 x 4 mm DIN 551, ISO 4766 Set Screws

Key Features & Benefits at a Glance

• Superior Holding Power: Made from high-strength alloy steel with a Rockwell B67 hardness rating, ensuring reliable, long-term fastening that resists loosening under vibration and load.
• Precise Thread Engagement: Class 6g thread fit provides consistent and accurate mating with nuts and tapped holes, reducing the risk of cross-threading and assembly errors.
• Optimized for High-Torque Applications: The slotted drive and headless design allow for a flush installation and are ideal for applications where space is limited and a secure, tamper-resistant fit is required.
• Enhanced Grip and Alignment: The flat tip design offers maximum surface contact, distributing force evenly to prevent damage to the shaft and improve component alignment.
• Robust and Durable Construction: The coarse thread (M4 x 0.7mm pitch) ensures faster installation and greater resistance to stripping in softer materials or under dynamic stresses.
• Guaranteed Quality and Consistency: Manufactured to meet DIN 551 and ISO 4766 standards, guaranteeing dimensional accuracy and performance reliability for professional use.
• Safe for Regulated Industries: Compliant with RoHS 3 and REACH regulations, making this set screw suitable for use in environmentally conscious and sensitive industrial applications.

Professional Applications & Engineering Value

This M4 x 0.7mm DIN 551 metric set screw is engineered to solve critical fastening challenges in demanding environments. Its alloy steel construction and Rockwell B67 hardness provide exceptional shear and tensile strength, preventing failure in high-stress assemblies like machinery, automotive components, and precision instruments. The headless, slotted design and flat tip are ideal for securing collars, gears, and pulleys onto shafts, ensuring a flush finish that eliminates protrusions and minimizes space requirements. The Class 6g thread fit and coarse thread profile enable quick, secure installation, reducing assembly time while maintaining a strong, vibration-resistant hold. This makes it a vital component for engineers seeking a reliable, RoHS and REACH compliant fastener for OEM and MRO applications where durability and precision are non-negotiable.
