Cyclone Tapping Screw

Cyclone's Higher Strip-to-Drive Ratio offers.

• Higher tightening torque for increased
  backout resistance
• Less stripping on the assembly line-fewer
  reworks or less scrap
• Possible use of thinner sheet metal
• Minimizes operator sensitivity
• Stall torques can be set higher
• No need for speed nuts or lock washers
• Uses standard hole sizes or smaller for
  even more strip torque
• Smooth bearing surface won't mar surface
  and resists potential corrosion problems
• High tightening torque even after removal and reinsertion
  

For Fastening works with metal-to-wood and metal to plastic.

Cyclone Tapping Screw

Compared to ordinary sheet metal screws, Cyclone bites into the tapping plate to increase
Strip Torque and Backout Resistance.

Tests Demonstrate Cyclone's Greater Strip Torque and Wider Operating Range

Test Details Screws: 8-18 x 1/2 Hex Washer Head, Zinc Plated R.P.M.: 1100 Axial Load: 25 Lbs. Bearing Plate: .030 Thick, S.A.E. 1010 Steel, .196" Clearance Hole Tapping Plate: .030 Thick, S.A.E. 1010 Steel, .125" Pilot Hole

Compare the Cyclone's Locking Efficiency to Ordinary Screws Test Details 8-18 x 1/2 Hex Washer Head, Zinc Plated Screws were Driven into .025 Thick Tapping Plates, S.A.E. 1010 Steel, using a .100 Pilot Hole. The Clearance Plate was .031 Thick, S.A.E. 1010 Steel, with a .196 Hole.

Cyclone Tapping Screw

Cyclone Teks combines a self-drilling point and an undercut head with a serrated helical shoulder to absorb high driving torque, making it the complete fastener for sheet metal ranging in thickness from .015" to .110". The unique combination of metal drilling and torque absorption provides a greatly increased safe operating range between drive and strip torques.

GER-NIB® FEATURE: For particularly torque-sensitive applications, Shakeproof's torque-robbing Ger-Nib feature can be incorporated in the Cyclone Teks head.

TEKS/2 POINT FASTENERS
AND CYCLONE TEKS/2 POINT FASTENERS

Tests involved 8-18 x 1/2 and 10-16 x 1/2 Hex Washer Head fasteners, with a .0002 zinc, clear chromate and wax finish, driven into a .020" and .030 SAE 1010 steel bearing plates and tapping plates (RB 45 hardness). Where used in bearing plates, clearance holes for number 8 Teks fasteners were .196" diameter, and for the number 10, were .220" diameter.

SIZES

Cyclone Teks fasteners are available in 6, 8, 10 and 1/4" diameter. Lengths, in relation to diameter, may be specified to meet application needs.

SELECTION GUIDE

Different diameters and types of Teks fasteners incorporate specific drill point lengths and designs that are capable of drilling a wide range of metal thicknesses. In the table below, the drilling capabilities of the Teks/2 point Teks and the Teks/3 point are provided as a guide.
