Minerallac 54416j Hex Head Cap Screw 3/8-16 X 1 in

Product Description

The MINERALLAC 54416j is a 3/8-16 x 1 inch hex head cap screw with full thread, manufactured from silicon bronze. Silicon bronze fasteners resist corrosion in wet, marine, and chemically active environments where carbon steel or zinc-plated hardware would fail prematurely. The coarse 3/8-16 thread pattern seats quickly and holds reliably in standard tapped holes and nuts. At 1 inch in length with full thread coverage from head to tip, this fastener delivers maximum thread engagement across the full grip range. Licensed electricians, plumbers, and mechanical contractors reach for silicon bronze hardware when ferrous fasteners are not appropriate for the installation environment.

This cap screw is suited for electrical enclosure assembly, conduit support hardware, grounding applications, and mechanical connections where corrosion resistance is a code or performance requirement. Silicon bronze is commonly specified for coastal, marine, pool, and wastewater installations. The hex head configuration accepts standard 9/16 inch open-end, box, or socket wrenches, making it compatible with typical trade toolkits. It is sold in jar quantity, making it practical for stocking and job-site use.

Key Features

• Silicon bronze construction provides superior corrosion resistance in marine, pool, and wet environments
• Full thread along the 1 inch shaft maximizes thread engagement for secure fastening
• Coarse 3/8-16 thread pattern for fast installation and broad nut and tap compatibility
• Hex head width of 9/16 inch accepts standard wrenches and sockets
• Head height of 0.234 inches provides a low-profile seating surface
• Jar packaging suitable for trade stocking and multi-unit installations

Compatibility

Designed as a standard 3/8-16 coarse-thread hex head cap screw for use in any application requiring a 3/8-16 fastener with silicon bronze material construction.

Installation Notes

Installation is performed by electricians, plumbers, or mechanical contractors depending on the application. Use a properly sized 9/16 inch wrench or socket to drive the fastener and avoid over-torquing, which can damage silicon bronze threads. Ensure mating threads or tapped holes are clean and free of debris before installation. When used in electrical applications, follow applicable NEC requirements for hardware material selection and grounding continuity.
