Jorset Concrete Screw -Technical Information:
The Jorset brand concrete screw cuts threads in a predrilled hole in concrete, brick or block. The screw has alternating raised and lowered threads with diamond cut notches which provide exceptional holding power and stability. The Jorset brand concrete screw is available in both 3/16", 1/4" or 3/8" diameters with either a flat phillips #3 countersunk or a 5/16" hex washer head. All screws are plated using the patented blue coating which provides extended life and additional lubricity for ease of installation.


Jorset Concrete Screw - Applications: Light to medium duty in concrete, brick and block.


Jorset Concrete Screw -Installation:
  • (1) Drill hole into base material using the drill bit provided with the screws. The depth of the hole must be at least 1/4" deeper than the Jorset embedment.
  • (2) Place object to be fastened over hole.
  • (3) Insert point of Jorset into hole and drive screw in using a nut drive or #3 bit tip. Do not over torque the screw.


Jorset Concrete Screw - Screw Length:
The length of the Jorset fastener to be used is determined by combining the thickness of the material to be attached with the desired depth of embedment in the base material. It is recommended that a minimum of 1" and a maximum of 1-3/4" embedment be used in determining fastener length. The diameter of the fastener and the depth of embedment affect pullout strengths. A carbide-tipped drill bit is supplied with each box of Jorset fasteners. The correct hole must be drilled for the screw to obtain holding values. In all cases the hole must be at least 1/4" deeper than the depth of the fastener embedment.
