S-92944A112 10-24 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh or humid industrial environments.
• Precise alignment and reduced wear thanks to the 1/4" shoulder diameter and standard shoulder fit, ensuring stable component positioning.
• High tensile and shear strength (70,000 psi tensile, 35,000 psi min shear) for reliable performance in heavy-duty mechanical assemblies.
• Easy installation and removal with the 5/32" hex drive and smooth flat head, allowing for efficient assembly with standard tools.
• Consistent thread engagement provided by Class 3A thread fit and UNC coarse threads, reducing the risk of cross-threading.
• Durable 82° countersink angle for a flush finish and improved load distribution in mating parts.
• Compliance with environmental regulations including RoHS 3 and REACH, ensuring safe use in global markets.

Professional Applications & Engineering Value

This 10-24 UNC shoulder screw is engineered to address common challenges in precision machinery, such as misalignment and component wear. The 18-8 stainless steel material offers excellent resistance to rust and corrosion, making it suitable for applications in automotive, aerospace, and food processing equipment where hygiene and durability are critical. The 1/4" shoulder diameter and 3/8" shoulder length provide a stable pivot or spacer, reducing friction and maintaining accurate alignment in rotating assemblies like gears and pulleys. Combined with the hex drive and flat head design, it ensures quick, secure fastening even in tight spaces, enhancing assembly efficiency and reducing downtime in industrial settings.
