Value Collection 3CBC906C0108 Carriage Bolt 3/8-16

Product Description

The VALUE COLLECTION 3CBC906C0108 is a fully threaded carriage bolt designed for general fastening applications in construction, woodworking, and mechanical assembly. It features a 3/8-16 UNC thread with a square neck under the domed head, which locks into material to prevent rotation during installation. The bolt is manufactured from Grade 1006-1050 steel with a galvanized zinc-plated finish for corrosion resistance. Conforming to ASME B18.5 standards, this bolt meets recognized dimensional and performance requirements. The 1-1/2 inch length under head suits medium-depth through-bolting tasks common in framing, equipment mounting, and structural connections.

This carriage bolt is suited for residential and light commercial construction, timber framing, decking, and general mechanical assembly. The square neck seats into wood or soft material to resist spinning without the need for a wrench on the bolt head. Fully threaded along the 1-1/2 inch shank length, it provides maximum thread engagement for thin-material or close-tolerance applications. Installers working with structural lumber, metal brackets, or equipment frames will find this bolt applicable across a wide range of trade and field scenarios.

Installation Notes

Carriage bolts are typically installed by tradespeople and general contractors using standard wrenches or sockets on the nut side. Before installation, ensure the mating material is properly drilled to allow the square neck to seat flush and prevent bolt rotation. A washer and nut are required on the threaded end and should be torqued per applicable project specifications. Follow all applicable building codes and manufacturer guidelines for structural fastening applications.
