Professional Applications & Engineering Value
These 5-40 UNC brass slotted rounded head screws deliver critical performance advantages in electrical components, marine hardware, and plumbing systems where corrosion resistance is paramount. The brass material inherently resists galvanic corrosion while maintaining excellent conductivity, making these fully threaded screws ideal for grounding applications and electronic enclosures. The coarse thread design ensures rapid installation in softer materials and prevents stripping in repeated assembly cycles. With 50,000 psi tensile strength, these industrial brass fasteners provide reliable clamping force in vibration-prone environments, while the rounded head profile eliminates sharp edges for improved safety in accessible locations.
Specification Summary & Compliance
Manufactured to ASME B18.6.3 specifications with Class 2A thread fit tolerance for consistent mating with corresponding nuts and threaded holes. The UNC coarse thread (5-40) with right-hand direction follows standardized inch system measurements. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures safe use across various industries. Dimensional accuracy maintained with 0.236" head diameter, 1-1/4" length, and standardized slotted drive configuration for tool compatibility.
