Value Collection 64661 1/4 Hex Lag Screw 1-1/2 in Stainless 18-8

Product Description

The VALUE COLLECTION 64661 is a 1/4-inch hex head lag screw intended for fastening applications where corrosion resistance is a priority. Manufactured from grade 18-8 stainless steel with an uncoated finish, this lag screw measures 1-1/2 inches in length under the head. The hex drive head allows installation with a standard hex socket or wrench, providing reliable torque transfer without the risk of cam-out. This fastener is suited for structural and general-purpose applications in environments where exposure to moisture or chemicals makes carbon steel fasteners a liability. Licensed tradespeople and experienced installers specify this grade when corrosion resistance and mechanical strength must be balanced.

This lag screw is appropriate for use in residential and light commercial construction, HVAC equipment mounting, plumbing support brackets, deck and outdoor structure fastening, and similar applications where stainless steel is required by specification or job conditions. The 18-8 grade designates an austenitic stainless alloy with good resistance to atmospheric corrosion, making it a practical choice in coastal or high-humidity environments. Installation into wood, composite, or similar substrates is typical for this fastener type and size.

Key Features

• Grade 18-8 stainless steel construction for corrosion resistance in wet or exposed environments
• Uncoated finish — no plating to chip, flake, or introduce galvanic incompatibility concerns
• 1/4-inch diameter with 1-1/2-inch length under head for shallow to medium-depth fastening
• Hex head drive accepts standard socket or open-end wrench for consistent torque application
• Lag thread profile designed for direct drive into wood or composite substrates

Compatibility

Designed as a standard 1/4-inch hex head lag screw suitable for general fastening applications in wood, composite, and similar materials where a 1-1/2-inch length under head and 18-8 stainless steel grade meet project or code requirements.

Installation Notes

Installation is typically performed by carpenters, HVAC technicians, plumbers, or general contractors using a hex socket driver or wrench. Pre-drilling a pilot hole is strongly recommended for wood substrates to prevent splitting and to reduce drive torque. Follow applicable building codes, equipment manufacturer instructions, and NEC or IPC guidelines where fastener specifications are referenced. Do not overtighten, as stainless steel fasteners are susceptible to galling if driven under excessive rotational force without lubrication.
