Q: Why can't I put a stainless steel Tapcon® screw into the base material more than 1-3/4"?

A: The maximum embedment for a Tapcon® is 1-3/4" because the lead thread on the screw is made to cut threads into the base material and wears down while doing so. After cutting threads into the base material for 1-3/4", the lead thread on the screw may not be hard enough to continue cutting. As a result, the Tapcon® may bind up in the hole and cause the head to shear off.

Q: Why are 410 stainless steel Tapcons magnetic?

A: The 410 stainless steel Tapcon® screws are magnetic because 400 series stainless steel contains steel and chromium without the presence of nickel.

Q: Does the 1/4" stainless steel Tapcon® use the same size bit as standard blue Tapcons?

A: Yes, all 1/4" Tapcons use a 3/16" bit. The only difference between the stainless steel Tapcons and the standard Tapcons is in the material that the screw is made from and the coatings applied to the screw.

Q: Can I use stainless steel Tapcons to attach a NO PARKING sign to an outdoor, concrete filled block wall?

A: Yes, stainless steel Tapcons can be used in block and are designed for outdoor use.

Q: Is the stainless steel hex head Tapcon® screw available in 3/16" diameter?

A: No, this stainless steel concrete screew is only made with a flat Philips countersunk head in the 3/16" diameter.
