The HILLMAN FASTENERS 829304 is a 100-pack of 3/8-16 stainless steel finished hex nuts designed for general fastening applications in trade and industrial environments. Each nut is machined to a finished hex profile, providing clean bearing surfaces and consistent thread engagement on 3/8-16 threaded rod, bolts, and studs. Stainless steel construction offers corrosion resistance in wet, coastal, or chemically exposed installations. These nuts are a standard choice for licensed tradespeople who need reliable, code-quality hardware in bulk quantities for plumbing, HVAC mounting, electrical enclosures, and structural attachments.
This 100-pack format suits contractors and service technicians who work through fasteners at volume on residential and light commercial jobs. The 3/8-16 thread is one of the most common unified coarse thread sizes in trade work, appearing in pipe hangers, equipment mounts, unistrut assemblies, and panel connections. Stainless steel grade construction makes these nuts suitable for outdoor, humid, or corrosive environments where zinc or plain steel fasteners would fail prematurely.
Designed for use with any standard 3/8-16 threaded fastener including bolts, threaded rod, and carriage bolts across HVAC, plumbing, and electrical mounting applications.
Installation requires a standard hex wrench or socket of the appropriate size for 3/8-16 hex nuts. Power down or de-energize any equipment before securing hardware to electrical enclosures or control panels. Follow applicable mechanical and building codes, including NEC and IFGC guidelines where fastener torque and material requirements are specified. Do not mix stainless steel fasteners with dissimilar metals in environments where galvanic corrosion could compromise the connection.
