S-97705A274 6-32 x 1/4" QQ-P-35, MS51021-23 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and extended service life.
• Exceptional holding power provided by the Class 3A thread fit, ensuring a tight, secure, and vibration-resistant connection.
• Easy and secure installation with the 1/16" hex drive, allowing for high torque application without cam-out in confined spaces.
• Enhanced grip and minimal surface damage from the cup point tip design, which bites into the shaft for reliable positioning.
• Broad compatibility with 6-32 UNC coarse threads, making it a versatile component for a wide range of American-standard assemblies.
• Space-saving headless design that sits flush against components, perfect for applications where clearance is limited.
• Guaranteed regulatory compliance, meeting Fed. Spec. QQ-P-35, RoHS 3, and REACH for safe use in regulated industries.

Professional Applications & Engineering Value

This 6-32 UNC stainless steel set screw is engineered to solve critical challenges in precision assembly and motion control systems. The 18-8 stainless steel material provides excellent resistance to rust and corrosion, making it suitable for use in demanding environments such as outdoor equipment, food processing machinery, and marine applications. The Class 3A thread fit and coarse thread design ensure a tighter tolerance and faster assembly compared to Class 2A, reducing the risk of loosening under vibration in pulleys, gears, and collars. The headless design with a 1/16" hex drive allows for installation in tight spaces where a protruding head is not feasible, while the cup point tip concentrates pressure to create a strong, non-slip grip on shafts, preventing component shift and maintaining precise alignment in high-torque applications.
