FOR PLASTICS & LIGHT ALLOYS

DSF1008

INTRODUCTIONDirect Screw Fixings provide a fast, economical, production line solution to fixing plastic and light alloy components where the need for re-use and high assembly torque is not a major factor.

The thread forms contained within this catalogue have been engineered to maximise the advantages of Direct Screw Fixings with forming screws for thermoplastics and light alloy materials and cutting types for use with thermosetting materials.

The adoption of these thread forms ensures that the margins between installation and stripping torque are optimised (an essential for trouble free installation) together with higher than normal re-usability - typically greater than 10 times-into thermoplastic materials, and maximum resistance to vibration.

The information in this catalogue is intended as a general guide. For further advice please consult your local PSM Sales Engineer or our Applications Engineers. The PSM Technology Centres can also provide pre-production test facilities for accurate performance data.

The TMP SERIES is a range of direct screw fasteners for use in thermoplastics. The key design aspects include a profiled thread root

to assist plastic flow, a 30° flank angle to reduce boss bursting forces and an 8° pitch angle which combine to give low installation torques with high stripping torques. For those applications not requiring the high levels of thread re-use and high clamping torque, (properties associated with threaded inserts) TMP screws offer an economical solution to plastics assembly and has distinct advantages over other direct screw fixings.

ADVANTAGES

The specialised equipment necessary to measure the effect of these factors is available at PSM's Technology Centres.This allows customers to obtain the best design possible.Pre-production testing is therefore strongly recommended.Please note the inclusion of a counterbore - this is important for the following reasons:

- Prevents damage to the top of the boss- Helps alignment of the screw in the boss- Assists in repeated assemblies of the screw- Acts as a relief for any material extruded to the head of the screw and allows flush finishes.

N.B. If moulded tool design or application into an existing boss renders the recommended boss design impractical,

please contact PSM for specific advice.

When choosing a direct screw fixing one of the major criterium is to obtain the maximum margin between driving torque and stripping torque. Screw design, material characteristics, moulding practice, hole size and installation speed all have an influence.

ASSEMBLY DATA RECOMMENDED INSTALLATION TOOL SPEEDS

To determine the optimum performance of direct screw fixings there are a number of influential factors which have to be considered if problems on the production line or in service are to be avoided. In order to establish the optimum clamping torque it is first necessary to establish the following:

1 Amount of torque required to form the first thread2 The amount of torque required for the screwhead to come into contact with the mating component.3 The amount of torque required for the joint to fail.

These figures should be obtained by the use of specialised equipment which simulates production line conditions since testing by hand omits the important effect of friction due to installation speed.PSM's Technology Centres are fully equipped to conduct these tests for you.

The repeat torque accuracy of the installation tool can vary and should always be considered when specifying the recommended clamping torque.

DIRECT SCREW FIXINGSTMP SERIES

TMP-04

The speed at which screws are installed should be carefully considered - speeds which are too high can destroy the material into which the screws are being driven.

Although a speed of 600rpm is recommended for most materials, pre-production testing and consultation with PSM should be undertaken for optimum results.

The application of plastics in engineering design is on the increase, which is why we offer the widest selection of inserts for plastics and every installation technique.Our applications Engineers are on hand to help you choose the most suitable fastener for your specific requirements, can offer pre-production test facilities and provide accurate performance data for your particular installation conditions.

Self-clinching fasteners for sheet metal provide deep tapped female threads or studs for use in conjunction with thin sheet metallic materials.Permanently attached to the parent material they allow the associated nut or bolt to be removed in service, without risk of the fastener becoming dislodged.This feature has already enabled a range of industries to streamline production methods and to fabricate complex shapes such as closed box sections.

Direct Screw Fixings are a fast, economical, production line solution for fixing plastic and light alloy components recommended where the need for re-use and high assembly torque are not major considerations.The range's unique thread forms have been engineered to maximise the advantages of Direct Screw Fixings.The range includes forming screws for thermoplastics/light alloy materials and cutting types for use with thermosetting materials.

The success of new materials is often dependent on the ability to devise methods of fixing and fastening. This is particularly true of mechanical fastening systems that allow dismantling for adjustment, servicing or repair. The fasteners shown here have been designed to meet the needs of designers who require the strength of a steel thread when using lightweight alloys such as magnesium and resin-based printed circuit boards.

P.S.M International's range of spring steel purpose designed pressings offer designers unique, cost effective fasteners include simple lineside assembly, multi-functional capability, high strength to weight performance and ability to assemble multi material types.
