The TIMco Shield Anchor Loose Bolts deliver professional-grade anchoring engineered for concrete, ...The TIMco Shield Anchor Loose Bolts deliver professional-grade anchoring engineered for concrete, brick and stone substrates. Featuring a three-segmented expansion mechanism and M10 metric threading, these Grade 8.8 bolts provide robust fixing solutions for demanding construction and maintenance applications. The torque-controlled design ensures secure installation with compatible metric threaded components, while the 135mm bolt length accommodates fixtures up to 75mm thick. The zinc finish with yellow passivation offers Corrosion Rating 1 protection, optimised for clean, dry and low-humidity environments. Supplied as loose bolts, this system enables component fixing through fixtures after shield installation, delivering enhanced flexibility for sequential assembly processes. Each bag contains 14 bolts engineered for reliable performance across professional and technical installations. Features include a three-segmented expansion anchor, Grade 8.8 bolt specification, 12mm fixture hole diameter, and 17mm socket size.
The TIMco Shield Anchor Loose Bolts (M10/75L) are engineered for trade professionals and serious DIYers requiring reliable, heavy-duty anchoring in solid materials like concrete, brick, and stone. Their primary benefit is the three-segmented expansion mechanism that provides exceptional grip strength for demanding construction and maintenance tasks. However, users should note that these bolts are best suited for dry, low-humidity environments, as their zinc yellow passivation offers only basic Corrosion Rating 1 protection.

FAQs
What size drill bit do I need for this anchor?
You must use a 12mm masonry drill bit for this M10 anchor.
Can I use these bolts outdoors?
No, these bolts have a Corrosion Rating 1 and are intended for clean, dry, and low-humidity indoor environments only.
What is the maximum fixture thickness this bolt can handle?
The 135mm total bolt length allows for fixtures up to 75mm thick.
Is the bolt included with the shield?
Yes, this is a complete loose bolt system containing both the shield and the expansion bolt.
What tool size is required to tighten the bolt?
Use a 17mm socket or spanner to secure the bolt.
Troubleshooting
Bolt rotates without tightening
The anchor expansion mechanism may not have set. Try removing the bolt and lightly tapping the shield further into the hole or check if the borehole is too wide.
Anchor pulls out of the hole
This often occurs in soft or crumbling masonry. Ensure you are using the bolt in solid material, not loose mortar joints, and that the hole diameter is exactly 12mm.
Pros and Cons
Pros
High load-bearing capacity with Grade 8.8 steel
Easy to install through the fixture due to loose bolt design
Reliable three-point expansion for secure anchoring
Standard M10 thread size ensures broad compatibility
Cons
Not suitable for outdoor or high-humidity environments
Requires a precise 12mm drill bit size
Limited corrosion resistance compared to stainless steel alternatives
Setup, Compatibility & Care
Drilling: Use a high-quality 12mm masonry drill bit to create a hole slightly deeper than the anchor length to accommodate potential debris.
Cleaning: Thoroughly blow or brush out the hole; clean holes are essential for the expansion segments to bite effectively.
Insertion: Place the shield into the hole. If it fits too tightly, ensure the borehole is perfectly straight.
Fixing: Position your fixture and insert the M10 bolt. Tighten using a 17mm socket wrench. Avoid overtightening past the point of firm resistance to prevent damage to the bolt threads.
Care: Keep bolts in their original packaging until use to prevent premature moisture exposure. For long-term performance, avoid using in damp basements or exterior masonry exposed to rain.
