The VALUE COLLECTION R6-32X5/8 is a 6-32 UNC pan head machine screw with a built-in silicone O-ring for self-sealing performance. The screw measures 5/8 inches in length under the head and is driven by a No. 2 Phillips bit. Constructed from 18-8 stainless steel with a bright, uncoated finish, this fastener resists corrosion in wet or chemically active environments. The silicone O-ring creates a seal at the mating surface, preventing fluid or gas intrusion through the fastener hole. Sold in a pack of 10, this screw is used by HVAC technicians, plumbers, and electricians wherever a watertight mechanical fastener is required in a threaded assembly.
This self-sealing machine screw is suited for light-duty panel, enclosure, and equipment assembly work across residential and commercial trade applications. Common uses include securing access panels, junction box covers, equipment housings, and control board enclosures where moisture ingress at the fastener point is a concern. The 6-32 thread size is widely encountered in electrical enclosures and light-gauge metal assemblies. The 18-8 stainless steel construction makes this screw appropriate for outdoor, humid, or corrosive-adjacent environments where carbon steel fasteners would degrade.
Designed as a standard 6-32 UNC pan head machine screw for use in threaded metal assemblies requiring a self-sealing fastener at the fastener hole.
Power down or de-energize any enclosure or equipment before fastening or removing screws near live components. Thread engagement should be sufficient to fully seat the O-ring against the mating surface for an effective seal. Avoid over-torquing, which can deform or extrude the silicone O-ring and compromise the seal. A No. 2 Phillips screwdriver or matching bit is required.
