Overview

The Minerallac 60402SSJ 1/4-20 Drop-In Anchor is a precision-engineered stainless steel fastener designed for secure, flush-mounted installations in metal, concrete, or masonry substrates. Constructed from corrosion-resistant 304 stainless steel, this anchor ensures long-term durability in harsh environments, including outdoor, marine, and industrial settings where moisture and chemical exposure are common. The 1/4-20 thread size provides compatibility with standard 1/4" bolts, while the 1" anchor length and 3/8" drill bit diameter allow for reliable embedment in substrates up to 1" deep. Ideal for electrical conduit, piping systems, and structural attachments, this drop-in anchor eliminates the need for protruding fasteners, creating a clean, flush surface. The anchor is installed by drilling a 3/8" hole, inserting the anchor, and setting it flush with a hammer or installation tool. Suitable for load-bearing applications up to the anchor's rated capacity, it is a cost-effective alternative to through-bolting in applications where backside access is limited. Common uses include securing junction boxes, cable trays, and HVAC components to concrete or metal surfaces.
