Professional Applications & Engineering Value

This 1/4 turn captive panel screw solves critical challenges in panel assembly where repeated access is required. The zinc-plated steel body combined with an 18-8 stainless steel retainer creates a durable fastener system that withstands vibration and frequent use without loosening or wearing out. The press-fit nut design eliminates the need for threading operations on delicate panels, preventing material stress and deformation. Engineered for industrial applications from electrical enclosures to machinery guards, it maintains secure panel mounting while allowing quick service access. The quarter-turn mechanism provides positive locking with minimal rotation, making it ideal for space-constrained installations where traditional screws would be impractical.

Specification Summary & Compliance

This captive panel screw features inch system measurements with precise dimensional tolerances for 0.437" inner panel holes and 0.25" outer panel holes. The assembly accommodates panel thicknesses from 0.13" to 0.15" with minimum 0.037" inner panel thickness. Manufactured to industrial standards with Phillips drive and rounded head configuration. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for safe use in global markets.
