Value Collection 781280PR Carriage Bolt 3/8-16 3/4 in 18-8 Ss

Product Description

The VALUE COLLECTION 781280PR is a 3/8-16 carriage bolt with a 3/4-inch length under the head, manufactured from 18-8 stainless steel with a bright, uncoated finish. The square neck beneath the domed head is designed to bite into material and resist rotation during installation, eliminating the need for a wrench on the bolt side. The 3/8-16 thread designation indicates a 3/8-inch nominal diameter with 16 threads per inch on a Unified National Coarse (UNC) thread form. This fastener is appropriate for structural assembly, maintenance, and fabrication tasks where corrosion resistance and a clean finished appearance are required.

Carriage bolts in this size and material grade are commonly used in light structural connections, wood-to-metal assemblies, equipment mounting, and general fabrication work in environments subject to moisture or chemical exposure. The 18-8 stainless steel construction makes this bolt well suited for outdoor, marine-adjacent, and food-service applications where carbon steel fasteners would corrode. Electricians, plumbers, HVAC technicians, and general contractors use fasteners of this type when securing equipment supports, brackets, and structural members. This part ships with a minimum order quantity of 100 pieces per package.

Key Features

• 3/8-16 UNC thread for broad compatibility with standard nuts and tapped holes
• 3/4-inch length under head for low-profile through-fastening applications
• Square neck prevents bolt rotation during nut tightening without requiring a second tool
• 18-8 stainless steel construction resists corrosion and oxidation in wet or exposed environments
• Bright, uncoated finish maintains dimensional accuracy and is compatible with stainless hardware
• Inch measurement system with UNC thread standard for domestic tool and hardware compatibility

Compatibility

Designed as a standard UNC carriage bolt for use with 3/8-16 stainless steel or compatible nuts and washers in general structural and mechanical assembly applications.

Installation Notes

Insert the bolt through a pre-drilled or pre-punched hole sized to allow the square neck to seat firmly and resist rotation. Tighten the mating nut with a standard wrench or socket; no tool is needed on the bolt head. When installing into wood, the square neck will draw into the material as the nut is torqued. Always pair stainless steel fasteners with stainless or compatible hardware to prevent galvanic corrosion.
