TAPTITE 2000® Fastener Design Guidlines

TAPTITE 2000® thread forming technology joins two unique concepts and advances fastener performance to new levels. TAPTITE 2000® fasteners afford end-users with enhanced opportunities to reduce the overall Cost of Assembly.

TAPTITE 2000® fasteners are designed to provide the benefits of prior TAPTITE® fastener products with an innovative new thread design - the Radius Profile™ Thread. The proven TRILOBULAR® principle is maintained while incorporating the Radius Profile™ thread. The result is a new generation of TAPTITE 2000® fasteners which provide excellent mechanical, assembly, and ergonomic characteristics surpassed by no other technology.

TAPTITE 2000® Technology

Lower Starting End Load

TAPTITE 2000® fasteners require a low axial end load to
initiate thread forming.

Higher Drive-to-Fail Ratio

The higher, more uniform drive-to-fail ratio of TAPTITE 2000® bolts provides a built-in safety factor against over-torquing.

TAPTITE 2000® HEAT TREATMENT

TAPTITE 2000® bolts perform well in large diameter sizes in deep thread engagements. In the past, the limitations of case-hardened products restricted the exploitation of in-place cost savings for larger-diameter TRILOBULAR® fasteners. However, TAPTITE 2000® screws and bolts are available with 3 different types of heat treatment: CORFLEX® - ‘I’, CORFLEX® - ‘N’, and case hardened, making the fasteners adaptable to a wider variety of applications.

CorflexCORFLEX® - ‘I’ Heat Treatment - CORFLEX® - ‘I’ TAPTITE 2000® bolts are neutral hardened to Class 8.8, 9.8, 10.9 or any intermediate value. The thread-forming zone is selectively induction hardened to form threads in untapped nuts. CORFLEX® - ‘I’ heat treatment allows TAPTITE 2000® thread rolling bolts to provide in-place cost savings in large structural applications with strength, ductility, and toughness equal to comparable machine screws or bolts. CORFLEX® - ‘I’ heat treatment to Class 10.9 level is standard for TAPTITE 2000® bolts size M6 (1/4”) and larger.

CORFLEX® - ‘N’ Heat Treatment - CORFLEX® - ‘N’ TAPTITE 2000® fasteners are neutral hardened to Class 10.9 strength level. CORFLEX® - ‘N’ products are designed for “soft white” metals such as aluminum or zinc alloys. CORFLEX® - ‘N’ heat treatment can be specified for any size TAPTITE 2000® screw or bolt that is intended to be used in aluminum or zinc alloys.

Case Hardening - Case hardening is the standard heat treatment for all TAPTITE 2000® screws in sizes M5 (#12) and smaller.

Inspection Procedures
Inspection Procedures

TRILOBULAR® products can be checked with standard micrometers for D and 60° V-anvil micrometers for C. Alternatively, C may be gauged using plain-hole ring gauges. These must have accurate holes as tabled for minimum and plus .025mm (.001 inch) for maximum.

Specials / Examples

Special Examples

TAPTITE 2000® fasteners can be manufactured with many popular internal and external drive systems to meet assembly requirements.

Coatings and Platings
Various coating and plating options can be applied to meet specific customer requirements for corrosion resistance and joint performance.

Lubrication
Lubrication is suggested for all thread-forming applications in metals. Please feel free to contact our Sales or Engineering Services Team for recommendations.
