Value Collection R52001188 Hex Lag Screw 3/8 X 4 in

Product Description

The VALUE COLLECTION R52001188 is a hex head lag screw used to fasten heavy materials to wood substrates in structural, mechanical, and general construction applications. The screw measures 3/8 inches in diameter with a 4-inch length under head and is manufactured from AISI 1006-1022 grade steel with a hot-dipped galvanized finish for corrosion resistance in exterior and treated-lumber environments. It meets ASME B18.2.1 dimensional standards. This fastener is installed by licensed contractors, general tradespeople, and experienced maintenance technicians where a high-strength, weather-resistant mechanical connection is required.

This lag screw is suited for residential and light commercial construction tasks including ledger-board attachment, structural framing connections, heavy timber work, and equipment anchoring to wood. The hot-dipped galvanized coating makes it appropriate for use with pressure-treated lumber where bare steel fasteners would corrode prematurely. It is a standard choice wherever ASME B18.2.1-compliant hex lag screws are specified on construction drawings or fastener schedules.

Key Features

• 3/8-inch diameter with 4-inch length under head for deep structural bite
• Hot-dipped galvanized finish provides corrosion resistance in exterior and treated-lumber applications
• Hex head drive accepts standard sockets and wrenches for high-torque installation
• Meets ASME B18.2.1 dimensional standards for consistent fitment and specification compliance
• AISI 1006-1022 grade steel construction for reliable mechanical strength

Compatibility

Designed as an OEM-style replacement or direct-specification fastener for applications requiring a 3/8-inch hex head lag screw conforming to ASME B18.2.1 in hot-dipped galvanized steel.

Installation Notes

Lag screws of this type are typically installed by carpenters, structural contractors, or maintenance technicians using a socket wrench or impact driver fitted with the correct hex socket. Pre-drilling a pilot hole sized appropriately for the shank and thread diameter is standard practice to prevent wood splitting and ensure full thread engagement. Follow applicable building code requirements, including those referenced in the IBC or local jurisdiction fastener schedules, for structural connections. Always confirm the galvanized coating is compatible with any chemical treatment present in the substrate lumber before installation.
