Value Collection R52001231 Hex Lag Screw 0.5in X 4in Galvanized

Product Description

The VALUE COLLECTION R52001231 is a hex head lag screw designed for heavy-duty fastening applications in wood, timber framing, and structural assemblies. Manufactured from AISI 1006-1022 grade steel with a hot-dipped galvanized finish, this fastener provides corrosion resistance suited for outdoor and moisture-exposed environments. The screw measures 0.5 inches in diameter with a 4-inch length under the head, conforming to ASME B18.2.1 dimensional standards. It is a standard choice for contractors, carpenters, and trade professionals who need a reliable, code-compliant lag fastener for structural connections.

This lag screw is used in residential and commercial construction where large-diameter wood fastening is required. Typical applications include ledger board attachments, deck framing, timber connections, and structural wood assemblies exposed to weather or high-moisture conditions. The hot-dipped galvanized coating makes it appropriate for pressure-treated lumber applications where corrosion resistance is a priority. This screw is sold individually with a minimum order quantity of 25 units.

Key Features

• Hot-dipped galvanized finish provides corrosion resistance for outdoor and pressure-treated lumber applications
• Hex head drive style accepts standard hex wrenches and impact drivers for high-torque installation
• Conforms to ASME B18.2.1 dimensional standards for consistent fitment and specification compliance
• AISI 1006-1022 material grade delivers adequate shear and tensile strength for structural wood connections
• 0.5-inch diameter and 4-inch under-head length suited for heavy timber and ledger board work

Compatibility

Designed as an OEM-style replacement and general-use fastener for structural wood assemblies requiring a 0.5-inch hex head lag screw conforming to ASME B18.2.1 standards.

Installation Notes

Installation is typically performed by carpenters, general contractors, or structural tradespeople using a hex socket or impact wrench. A pilot hole should be drilled prior to driving the screw to prevent wood splitting and to reduce drive torque. Power down or secure the work area before drilling and fastening. Follow applicable building codes and load tables for structural lag screw connections.
