The JCP Construction Products Heavy Duty Anchors are engineered for professional contractors and structural installers who require high-performance, long-lasting fixings for heavy-load applications. These anchors provide exceptional load-bearing strength and superior corrosion resistance due to their A4-316 stainless steel construction, making them ideal for exterior or harsh environments. A notable caveat for users is that the high-strength stainless steel requires precise hole drilling and torque application to ensure the anchor expands correctly according to ETA specifications.

A4-316 stainless steel offers high resistance, but for permanent underwater or submerged applications, check for specific marine-grade chemical compatibility.
These anchors are designed for structural concrete; they are not recommended for hollow brick or aerated concrete blocks.
Yes, 151 represents the total length of the anchor assembly.
It is a European Technical Assessment certification confirming the anchor is suitable for use in both cracked and non-cracked concrete.
These are intended for permanent structural fixing. Removal would require cutting the bolt, which may damage the surrounding concrete.
The hole was likely drilled slightly too large or the anchor has not expanded; ensure the drill bit matches the specified diameter and is in good condition.
Ensure the hole is clear of all concrete dust, which can build up and prevent the expansion clip from seating correctly.
To achieve the certified performance, users must drill a hole consistent with the 18mm anchor diameter. Use a rotary hammer drill and ensure the hole is cleared of dust and debris before insertion, as residual dust can impede the expansion mechanism.
