DESIGN GUIDE

Tips for investigating a Fastener Problem:

Get as much information as possible:

    • Where and how are the parts used?
    • Have you bought these parts for a long time?
    • Are you the sole customer of this part?
    • Request samples of failed parts
    • Are unused parts available from the same lot? If yes, request some.
    • How many parts are used in the assembly?
    • Is there any pattern to the failures – for example, are they failing in a single location?
    • What type of driver is being used?
    • What torque value is being used to install the parts?
    • Request pictures of failed parts and the assembly
    • If possible, allow the supplier to visit and observe the problem first-hand.
    • How best would you describe the problem?
    • Has anything recently changed or something unique occurred?
Tap/R fastener

Tap/R®

A graduated thread rolling area, less driving torque is required to install this 360 degree thread forming screw.

Taptite fastener

Taptite®

The unique “tri-lobular” shape roll forms a mating thread in an unthreaded pilot hole.

Cyclone tapping screw

Cyclone®

Stripping problems & scrap loss reduced with the unique serrated shoulder under head.

Hurricane screw

Hurricane®

Serrations under the head creates a positive torque brake when this anti-strip screw is driven into thin sheet metal, aluminum or plastic.

Field Ready™

Tunable torque design allows screws to be shipped in the “Field Ready” position.

Shakeproof screw

Shakeproof™ Thread

A curve added to the helix of the threads keeps the screw secure for life, eliminating prevailing torque nuts & nylon patches.

GXSelf Extruding screw

GX®

The eccentric thread section extrudes thin sheet metal upward and downward increasing the thread engagement area and torque absorption capability.

Thread cutting screws

Thread Cutting Screws

A shank slot in the body of the screw provides true cutting action eliminating a separate tapping operation generating a perfectly mated thread that is reusable.

Designing Threaded Fasteners in Plastic

BosScrew Fastener

BosScrew™

A screw for plastics that will not loosen! The pressure flanks on threads are engineered to not loosen over time, with temperature changes, under vibration.

HI-LO Fastener

Hi-Lo®

A double lead high and low thread form increases performance in low density material.

HI-LO Plus Fastener

Hi-Lo Plus®

Sharper angles on the threads penetrate deeply without weakening plastic materials through stress-caused fracturing.

Plastite Fasteners

Plastite®

Tri-lobular thread rolling screw for plastics.
