The VALUE COLLECTION R63091029 is a 1/4-20 x 1 inch brass hex head cap screw with a Unified National Coarse (UNC) thread standard. The 1-inch dimension refers to the length under the head. Brass construction provides natural corrosion resistance and moderate strength, making it suitable for applications where galvanic compatibility with non-ferrous components is required. The 7/16-inch hex drive accepts a standard wrench or socket. Licensed tradespeople and maintenance technicians working in plumbing, HVAC, and light electrical applications commonly use this fastener when steel is not appropriate due to material compatibility or corrosion concerns.
This cap screw is suited for residential and light commercial maintenance, repair, and assembly work. Common applications include panel mounting, equipment brackets, pipe hangers, and general fastening tasks where a non-magnetic or corrosion-resistant fastener is preferred. The UNC thread form is widely used in inch-based mechanical assemblies throughout the trades.
Designed as a standard 1/4-20 UNC inch-series hex head cap screw for use in any application requiring brass fasteners with this thread size and length.
Install using a 7/16-inch wrench or socket driver. Power down or de-energize any equipment before fastening hardware near electrical components. Follow applicable mechanical and electrical codes, including NEC where relevant, when using fasteners in panel or enclosure assemblies. Do not over-torque brass fasteners, as the material is softer than steel and susceptible to thread damage.
