Value Collection 489133PS Carriage Bolt 1/2-13 10 in

Product Description

The VALUE COLLECTION 489133PS is a 1/2-13 UNC carriage bolt with a 10-inch length under head, designed for structural fastening in wood, metal, and composite assemblies. The square neck beneath the domed head resists rotation during installation, eliminating the need for a wrench on the bolt side. Manufactured from Grade 2 steel with a zinc-plated finish, this bolt provides adequate strength for general-purpose applications and baseline corrosion resistance in dry or mildly humid environments. It meets ASTM A307 standards for low-carbon steel fasteners.

This carriage bolt is used in a wide range of trade and construction applications including framing connections, equipment mounting, fence and gate hardware, and structural wood-to-wood or wood-to-metal joints. The 10-inch length under head suits assemblies requiring fastening through thick stock or stacked members. Electricians, plumbers, HVAC technicians, and general contractors reach for this fastener when securing equipment supports, strut channels, or utility structures where a flush, round-head bolt profile is required.

Key Features

• 1/2-13 UNC thread for broad nut and hardware compatibility
• Square neck locks bolt in place during tightening — no back-wrench needed
• 10-inch length under head suits deep-stack or thick-member assemblies
• Grade 2 steel construction meets ASTM A307 low-carbon fastener standard
• Zinc-plated finish provides baseline corrosion resistance in interior and sheltered applications

Compatibility

Designed as a general-purpose UNC carriage bolt for use with standard 1/2-13 nuts and washers in structural, equipment-support, and utility fastening applications.

Installation Notes

Installation requires a standard socket or open-end wrench on the mating nut; no tool is needed on the bolt head when the square neck is properly seated in the substrate. Always pre-drill a correctly sized hole so the square neck draws flush and locks without splitting the material. Power down and de-energize any equipment before fastening through or near electrical enclosures or panels. Follow applicable local building codes and torque guidelines for the connected assembly.
