Stewart Fastener 5020 Hex Nut Lok Bolt 3/8 X 3 Inch

Product Description

The STEWART FASTENER 5020 is a 3/8-inch by 3-inch hex nut lok bolt, also known as a Rawl-style anchor bolt, used to secure equipment, fixtures, and structural components to concrete or masonry substrates. The 3/8-inch diameter and 3-inch length make it suitable for medium-duty anchoring applications where a reliable mechanical hold is required. Installation is completed with standard hex drive tooling. This type of fastener is commonly installed by HVAC mechanics, plumbers, electricians, and general contractors when anchoring equipment bases, pipe hangers, or electrical enclosures to concrete slabs and block walls.

This lok bolt anchor is appropriate for use in both residential and light commercial settings where concrete or masonry anchoring is required. Typical applications include securing equipment pads, conduit supports, pipe straps, and mechanical room fixtures. The hex nut drive style allows for straightforward tightening with a standard wrench or socket set without specialized tooling.

Installation Notes

Installation of expansion-style anchor bolts in concrete or masonry should be performed by a qualified tradesperson following applicable local building codes. Drill the correct diameter hole to the required depth before setting the anchor, and clear debris from the hole before insertion. Do not overtighten the hex nut, as this can damage the substrate or compromise the anchor hold. Always verify the substrate condition and anchor load rating is appropriate for the intended application before installation.
