Staytite nuts

Easy to fit

Every Staytite nut is assembled with astainless steel spring insert. As the nutis installed on the screw thread, thestainless steel spring insert engages withthe base of the screw thread and flexesupwards. This gives the nut a lowerinstallation torque compared to othertypes of self-locking nut, particularlythose of the deformed thread type.

Resistant to vibration

and loosening

During use the Staytite nut resistsvibration and loosening because theinsert flexes downwards and is ‘pulled’into closer contact with the screwthread by the upwards anti-clockwiserotation of the nut body. This alsoproduces a very effective interferencefit between the threads of the nut andof the screw.

Excellent value

The nut has a thin profile which enablesthe use of smaller, less costly bolts.

Weldable

Staytite nuts

The Staytite weldable collarnut has a self locking ring inthe collar

The nut is suitable if you have aproblem installing a lock nut with abolt whereby you can’t reach the boltto install a lock nut.

The nut can be spot welded easily toyour product and then the bolttightened into the nut. This gives youan instant locking and anti vibrationassembly.

Bi-way nuts

Bi-way nut is a two-wayreversible self-locking lock nut

Efficient locking

It features side indentations whichslightly distort the centre thread. Thiscreates a locking action when thedistorted threads engage the threadsof the mating part.

Reduced production cost

The top and bottom of the nut are thesame. This means the nut can beassembled from either side whichreduces assembly and production costs.

Manufactured in accordance with DIN980V performance

Hardlock nuts

Hardlock Nut is a combinationof a concave upper nut andconvex lower nut

Secure and

anti-loosening

The nuts resist loosening inenvironments where high vibrationoccurs. They provide a securefastening to many applicationsincluding railways, civil engineering,radar, power masts, pylons, windturbine towers and masts.

Low lifetime cost

The reliable nuts require less inspectionand maintenance than traditional nutsand users can reduce associated costs.

Hardlock nuts with flange are alsoavailable. For further details pleaserequest a copy of our Hardlockbrochure or give us a call.

Hardlock nuts

How it works:

The concave upper nut is threadeddown until the concentric conicalrecess comes into contact with theeccentric conical protrusion of theconvex lower nut.

The convex lower nut is heldstationary, either by being seated, orby being held stationary with aspanner if seating is not required.

When the convex upper nut is tightenedto the recommended tighteningtorque, locking forces between theupper and lower nuts are induced.

Installation Hints:

• Make sure all parts and threads areclean and undamaged therebyensuring the best assembly. Threadaccuracy is 6H.

• ANTI-SEIZE lubricant isrecommended on all bolts and/orshafts along with the nut to preventgalling and seizing.

• It is desirable to have at least twothreads extended beyond the top ofthe new assembly.

• For fastening refer to the tighteningtorque table.

• Never install or remove both upperand lower nuts simultaneously.

Use a spanner to tighten the convexnut to the correct torque. (see chart)

Thread down the concave nut onto theconvex nut manually.

Tighten the concave nut with thespanner, about one turn. (see chart)

If the concave nut is not sufficiently tightened, it may become loose.

Designed to cut their ownmating thread as they aredriven into the material

Materials• Hardened Steel • Stainless Steel

Thread Cutting Screws

for Plastics

• Type BT or 25 has a blunt, tapered point, and a wide milled cutting slot.

• Type BF has a blunt, tapered point, with multiple flutes.

• Type Y has a spaced thread and pilot point similar to Type B but with the addition of five cutting flutes extending the full length of the shank.

We have a wide selection of heads anddrives available for our self tapping,thread cutting and thread formingscrews. Please contact us with yourspecific requirements.

Thread forming screws do not removeany material, rather, the processdisplaces the materials to generate thethread form. The screw has a taperedpoint, which, as it enters the pilothole, widens the hole and compressesthe displaced material.

Thread Forming

screws

Quick and easy process

• One operation is eliminated as nothread tapping is required

• Suitable for use in metal, plastic orwood.

Types Available

HI-LOW A twin thread hardened screw wherethe angle and height of one thread isdifferent to the other.

Twin threads enable a faster insertionof the screw and features a lowerinsertion torque.

• ‘LOW’ thread reduces risk ofsplitting and cracking material.

• ‘HIGH’ thread significantlyincreases resistance to stripping.

• Available with blunt or gimlet point.

Trilobular thread forming screws formetal or plastic.

• Perfectly mated threads, mean agreater resistance to pull outvibration.

30° thread angle TV Screw• For soft and medium density

plastics.• Avoids splitting of mating material.
