Masonry Screws Evolution Blue with Evoshield 500HR Coating
Masonry Screws Evolution Blue with Evoshield 500HR Coating are highโperformance, heavyโduty concrete
and masonry screws designed for fast, reliable fixing into concrete, brick, block and stone โ
without the need for traditional plugs. The advanced blue Evoshield 500HR corrosionโresistant
coating offers longโlasting performance in demanding internal and external environments, making
these masonry anchors ideal for professional trade use.
Evolution Blue Masonry Screws with Evoshield 500HR Coating are purposeโdesigned concrete screws
for rapid, safe and dependable fixing into a wide range of masonry substrates. Unlike traditional
plugโandโscrew systems, these anchors cut their own mating thread directly into the base material,
enabling quicker installation and a more secure, vibrationโresistant connection.
The specialised hardened steel core and deep cutting thread provide excellent pullโout and shear
performance when installed correctly into suitable concrete or brickwork. The distinctive blue
Evoshield 500HR coating delivers advanced corrosion resistance, making these fixings well suited
to both internal and many external applications, including damp or semiโexposed environments
(subject to project design and local conditions).
Common uses include fixing brackets, conduit clips, trunking, unistrut, timber battens, door
frames, window frames, handrails, light structural supports and a wide range of building
components directly to masonry. With no need for plugs and only a single installation step
after drilling the pilot hole, Evolution Blue Masonry Screws help speed up work on site while
maintaining consistent, professional results.
Typical Use Cases
- Fixing timber battens or grounds to concrete and brick walls for drylining or cladding systems.
- Securing metal brackets, cable trays, trunking and pipe clips to concrete soffits and walls.
- Anchoring door frames, window frames and thresholds to masonry reveals.
- Mounting handrails, guardrails, balustrade bases and light structural components (subject to engineering approval).
- General M&E and firstโfix installations where quick, reliable masonry fixings are required.
Installation & Usage Tips
- Drill correct pilot hole: Use a suitable masonry drill bit of the diameter specified for the screw size. A tightโtolerance pilot is essential for performance.
- Correct embedment depth: Ensure the screw penetrates sufficiently into sound masonry (as per manufacturerโs guidance) after allowing for fixture thickness and any clearance.
- Clean the hole: Remove dust and debris from the drilled hole (e.g. by blowing out or vacuuming) to maximise holding power.
- Avoid weak substrates: Do not install into cracked, severely weakened or friable masonry without checking suitability. Use alternative fixings where required.
- Driving method: Use a suitable impact driver or drill/driver with the correct bit type. Drive the screw steadily โ do not exceed recommended torque to avoid overtightening or stripping the substrate.
- Edge and spacing distances: Observe minimum edge distances and spacing between fixings as per the technical data sheet to maintain load capacity.
- External exposure: While Evoshield 500HR offers enhanced corrosion protection, always confirm suitability for your specific exposure class and design life requirements.

Masonry Screws Evolution Blue With Evoshield 500HR Coating Frequently Asked Questions (FAQs)
1. Do Masonry Screws Evolution Blue with Evoshield 500HR Coating need plugs?
No. These are plugโfree masonry screws. Once you have drilled the correct pilot hole, the screw cuts its own
thread into the substrate. This simplifies the fixing process and reduces the number of components you need
to carry and handle on site.
2. What substrates are these masonry screws suitable for?
They are typically suitable for use in goodโquality concrete, solid brick, dense block and some natural stone.
Do not use in very soft, hollow or highly friable materials without checking the manufacturerโs guidance. For
lightweight block or aerated concrete, specialist fixings may be more appropriate.
3. Are Evolution Blue Evoshield 500HR screws suitable for outdoor use?
The Evoshield 500HR coating is designed to offer enhanced corrosion resistance, making these screws suitable
for many internal and external applications. However, you should always check the manufacturerโs data regarding
exposure class and design life, especially in coastal, industrial or highly corrosive environments.
4. What drill bit size should I use?
The correct pilot hole diameter depends on the screw diameter and the base material. As a guide, manufacturers
usually specify a slightly smaller drill diameter than the screwโs outer thread diameter. Always follow the
drill size recommendations given on the packaging or data sheet for your specific masonry screw.
5. Can these masonry screws be removed and reused?
The screws can usually be removed for inspection or adjustment, provided the substrate has not been stripped
or damaged. Reโuse in the same hole is not generally recommended where structural loads are involved. For
permanent or safetyโcritical applications, always follow the manufacturerโs and engineerโs recommendations.
Common Uses / How to Use
To achieve the best results with Masonry Screws Evolution Blue with Evoshield 500HR Coating:
- Mark the fixing positions and ensure minimum edge distances and spacing are observed.
- Select the correct masonry drill bit size for the screw diameter and base material.
- Drill a straight pilot hole to the required depth, allowing for fixture thickness and embedment.
- Clean the hole thoroughly to remove dust and debris.
- Position the fixture (e.g. bracket, batten, frame) over the hole.
- Insert the screw through the fixture and drive it into the hole using a suitable driver bit.
- Tighten until the fixture is firmly clamped without overtightening or stripping the substrate.
