Value Collection R63234028 Hex Lag Screw 5/16 in Stainless

Product Description

The VALUE COLLECTION R63234028 is a hex head lag screw designed for heavy-duty fastening applications in wood and similar substrate materials. At 5/16 inches in diameter with a 3-1/2 inches length under head, this screw provides substantial holding strength for structural and general trade installations. Constructed from grade 18-8 stainless steel with an uncoated finish, it offers reliable corrosion resistance in environments where moisture exposure is a concern. This fastener is used by contractors, plumbers, electricians, and HVAC technicians for securing equipment supports, brackets, and structural members.

Hex head lag screws in this size range are commonly used in both residential and light commercial applications. Typical installations include mounting pipe hangers, equipment pads, electrical panel supports, and structural blocking. The 5/16 inches diameter and 3-1/2 inches under-head length make this screw suitable for moderate-depth fastening into wood framing and engineered lumber. The hex drive head allows installation with standard wrenches or impact drivers, making it a practical choice for field work.

Key Features

• Grade 18-8 stainless steel construction for corrosion resistance in wet or outdoor environments
• 5/16 inches diameter with 3-1/2 inches length under head for solid holding depth
• Hex head drive compatible with standard wrenches and impact drivers
• Uncoated finish suitable for stainless-to-stainless or mixed-material assemblies

Compatibility

Designed as a general-purpose hex head lag screw for wood framing, structural blocking, and equipment mounting applications across HVAC, plumbing, electrical, and general construction trades.

Installation Notes

Installation is typically performed by licensed tradespeople or qualified contractors using a hex wrench, socket, or impact driver sized to the fastener head. Pre-drilling a pilot hole into the substrate is strongly recommended to prevent wood splitting and to achieve proper seating depth. Always disengage power tools and de-energize any nearby electrical systems before driving fasteners near live circuits. Follow applicable local building codes and manufacturer guidelines for fastener spacing and load requirements.
