Professional Applications & Engineering Value
This 3-48 UNC shoulder screw is engineered to address critical challenges in precision machinery, automation systems, and heavy-duty equipment. The 316 Stainless Steel material provides exceptional resistance to corrosion and chemical exposure, making it suitable for marine, chemical processing, and outdoor applications. The Black Oxide finish not only enhances aesthetic appeal but also reduces friction and galling during installation. With a Class 3A thread fit and coarse UNC thread, it ensures quick assembly and reliable performance under dynamic loads. The hex socket head and knurled texture facilitate easy handling in confined spaces, reducing installation time and improving operational efficiency. Ideal for use in pivots, axles, and guiding mechanisms, this screw delivers consistent tensile and shear strength, minimizing downtime and maintenance costs.
Specification Summary & Compliance
This shoulder screw adheres to UNC thread standards with a Class 3A thread fit for high precision. Key dimensional tolerances include a shoulder diameter of 1/8" with a tolerance of -0.004" to -0.002" and a shoulder length of 3/4" with a tolerance of -0.005" to 0.005". It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances and suitable for global industrial markets.
