Professional Applications & Engineering Value
This 18-8 stainless steel captive panel screw addresses critical challenges in electronic enclosures, machinery panels, and access covers where vibration resistance and repeated access are paramount. The knurled socket head provides exceptional torque transmission while the 1/4"-28 UNF fine threading with Class 3A fit maintains precise alignment in threaded receptacles, preventing cross-threading during frequent maintenance cycles. The partially threaded design ensures consistent panel spacing while the 70,000 psi tensile strength guarantees structural integrity in high-stress industrial environments, making it ideal for telecommunications, automotive, and heavy equipment applications where reliability cannot be compromised.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 3A thread fit and UNF fine threading (1/4"-28), this captive panel screw maintains length tolerance of -0.03" to 0" for consistent installation. The product fully complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in global industrial markets. The 18-8 stainless steel construction meets industry standards for corrosion resistance and mechanical performance in captive panel applications.
