Value Collection 215068MSC Carriage Bolt 1/4-20 Grade 8

Product Description

The VALUE COLLECTION 215068MSC is a Grade 8 alloy steel carriage bolt sized at 1/4-20 with a 1-1/4 inch length under head. It features a square neck that locks the fastener in place against the bearing surface to prevent rotation during installation. Fully threaded along its entire shank and left uncoated, this bolt is built to UNC thread standard and meets SAE J429 requirements for high-strength fastener applications. It is suited for structural assemblies, equipment mounting, and general mechanical work where a high-strength fastener with a low-profile dome head is required.

This carriage bolt is appropriate for residential and light commercial construction, equipment fabrication, and industrial maintenance tasks. The Grade 8 alloy steel construction makes it a dependable choice where tensile strength and resistance to shear forces are priorities. It is sold in packages of 100, making it practical for production or batch installation work. Tradespeople in carpentry, millwright, and general mechanical service will find this fastener fits standard through-hole applications across wood, metal, and composite materials.

Key Features

• 1/4-20 UNC thread size with 1-1/4 inch length under head for precise fitment in standard applications
• Fully threaded shank provides maximum thread engagement along the entire bolt length
• Grade 8 alloy steel construction delivers high tensile strength per SAE J429
• Square neck design resists rotation during nut installation without requiring a wrench on the bolt head
• Uncoated finish for bare metal use or for situations where a specific coating will be applied in the field
• Sold in 100-count packages to support production and batch fastening work

Compatibility

Designed as a standard 1/4-20 UNC carriage bolt suitable for through-hole fastening applications in wood, metal, and composite assemblies where a Grade 8 high-strength fastener is specified.

Installation Notes

Installation is typically performed by carpenters, millwrights, or general mechanical technicians using standard hand tools. Insert the bolt through a pre-drilled clearance hole so the square neck seats fully into the material, preventing rotation before threading and tightening the nut. Follow applicable torque specifications from published Grade 8 fastener tables or project engineering documents. De-energize any associated electrical or mechanical systems before working on assemblies where this fastener is part of structural or safety-critical joints.
