S-98511A739 M4 x 12 mm Aluminum Socket Head Screws

Key Features & Benefits at a Glance

• Superior strength-to-weight ratio from 7075 aluminum construction, ideal for applications where reducing weight without sacrificing durability is critical.
• Precise Class 3A thread fit ensures reliable engagement and consistent clamping force, minimizing the risk of loosening in high-vibration environments.
• Corrosion-resistant aluminum material provides excellent long-term performance without the need for additional plating or coating.
• Standard hex socket drive (3mm) allows for high-torque installation and a clean, flush finish in counterbored holes.
• Fully threaded design (M4 x 0.7mm) offers maximum grip length and versatility for a wide range of material thicknesses.
• Compliance with RoHS 3 and REACH regulations guarantees the fastener is free from hazardous substances, making it suitable for global markets and sensitive applications.
• Coarse thread pitch enables quicker assembly and reduces the risk of cross-threading compared to fine-pitch alternatives.

Professional Applications & Engineering Value

Engineered for demanding environments, these M4 socket head cap screws in 7075 aluminum solve critical challenges in lightweight structural assemblies, robotics, and precision instrumentation. The Class 3A thread fit and coarse thread pitch provide exceptional resistance to vibrational loosening, a common failure point in dynamic systems. The hex socket drive accommodates high installation torque, ensuring a secure fit in tight spaces where a protruding head is not feasible. This combination of a high-strength aluminum alloy and precision metric threading delivers a reliable, corrosion-resistant fastener that maintains integrity under stress without adding unnecessary weight, making it an optimal choice for aerospace prototypes, electronic enclosures, and automated machinery.

Specification Summary & Compliance

This socket head cap screw adheres to precise metric dimensional standards with an M4x0.7mm coarse thread and a Class 3A thread fit for superior accuracy. The manufacturing and material composition are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and unrestricted use in industrial and consumer products.
