Professional Applications & Engineering Value
These 1-72 UNF brass screws deliver exceptional value in precision assembly applications where corrosion resistance and electrical conductivity are critical. The rounded head slotted design combines traditional tool compatibility with modern aesthetic requirements, while the fully threaded right-hand configuration ensures maximum thread engagement in thin materials. Engineered with fine threading and Class 2A thread fit, these fasteners prevent loosening in vibrating environments common to electronics, instrumentation, and marine equipment. The brass material naturally resists galvanic corrosion when paired with dissimilar metals, making these screws ideal for electrical panels, communication devices, and precision mechanical assemblies where reliability cannot be compromised.
Specification Summary & Compliance
Manufactured to exacting ASME B18.6.3 standards with Class 2A thread tolerances for consistent fit and performance. The 1-72 UNF fine thread specification ensures precision engagement in applications requiring fine adjustment capabilities. Regulatory compliance includes RoHS 3 (2015/863/EU) with exemption 6(c) for lead in copper alloy and full REACH (EC 1907/2006) adherence as of January 17, 2023. All dimensional specifications including 0.137" head diameter, 1/4" length, and 0.073" thread diameter maintain strict industrial tolerances for reliable interchangeability.
