The BAPP Group of Companies founded in 1972 has now become the largest independent stockist and distributor of industrial fasteners and associated products in the UK
BAPP are fully approved as a manufacturer, by Lloyds Register, to produce CE marked fastenings to BS:EN14399 and BS:EN15048. The company is at the leading edge of EC fastener legislation. We offer all of our clients a full 24-hour technical advice service and we aggressively pursue cost-down through ‘value engineering’ with them.
Service is truly the backbone of our offering and is probably the single biggest factor in our growth to becoming a £26M fastener business. The company carries stock valued in excess of £5M within our global distribution centres. We have grown by being flexible and agile enough to respond to our customer’s most urgent needs. BAPP has exported its fastenings to jobsites and factories across the globe for over 20 years gaining invaluable experience and expertise and winning accolades for its competence in complex Project Management tasks.
At BAPP high quality fasteners are extremely competitively priced. We recognise and understand the efforts of senior executives everywhere to reduce costs, whilst maintaining optimum product integrity. To that end BAPP was one of the first European fastener companies to global outsource its manufacturing. Over the past 30 years intimate partnerships have been established with our ‘supply side’.
Our manufacturing philosophy is a facet of our business that differentiates us from our competitors. All of our partner factories are annually audited and provide components in strict compliance with the 110 page ‘BAPP Specification Handbook’, detailing everything from the stringent tests that need to be carried out to the world-class packaging and documentation for which we are well known.
Finally, I can assure you with certainty that BAPP will never promise anything that we knowingly cannot achieve and I hope that the contents of this document will both reassure you and assist us bothin developing a mutually successful partnership together. Dean G CookChairman
BAPP Group Limited is an extremely successful business, having grown organically since its inception over 40 years ago, to become the UK’s largest supplier and stockist of industrial fasteners to the Engineering, Construction and Offshore sectors.

Developed for more simplified bolt fastening and more accurate performance. HRC (Tension Control) Bolts offer excellent characteristics as shown below.
1. Controlled clamping force can be ensured. 2. Completion of bolt fastening can be confirmed by the shear-off of the notched end of the bolt. 3. Removes the possibility of operator error.4. Fastening can easily be done by electric wrench. 5. Noiseless installation and no need of wrench adjustment. 6. The bolt does not rotate when fastening.
Features of High Strength HRC (Tension Control) Bolts
The bolt reacts to the fastening torque and the notched end of the bolt shears off. The required clamping force is thus given.

Sample Nut Marking Sample Bolt Marking
Galvanised HRC Assemblies, (bolts, nuts and washers)are supplied in a fully assembled condition ready for use. No treatments such as T-Washing or Etching can be applied before installation as this will change the tightening characteristics and prevent the correct preload being achieved.
The components of the assembly, as supplied, have been tested as a batch and must not be mixed with components from any other batch of HRC assemblies.
Care must always be taken to avoid any contamination of the assemblies with anything that may change the lubrication of the nut, bolt thread or washer.
SUCH CONTAMINATION WILL EFFECT THE ASSEMBLY PRELOAD THAT IS ACHIEVED DURING TIGHTENING.
Although HRC assemblies are designed to withstand the maximum preloads that can occur when contaminated with water, we would advise that tightening of HRC assemblies is avoided in the rain.

STEELWORk FIxINGSFor over 75 years Lindapter has pioneered the design and manufacture of quality steel work connection solutions, providing a unique and proven concept: innovative clamping systems that eliminate the need to drill or weld steelwork, reducing installation time and labour costs. Lindapter steelwork fixings and Girder Clamps are ideally suited for both new construction and the refurbishment of existing structures.
CAVITy FIxINGSThe range consists of the legendary Hollo-Bolt® and Lindibolt®, creating simple, cost-effective connections of SHS and other hollow sections, or conventional steelwork where access is available from one side only. The Hollo-Bolt can be used as a primary structural connection as detailed in the SCI/BCSA publication ‘Joints in Steel Construction – Simple Connections’.
SUPPORT FIxINGSLindapter provides solutions for supporting all building services, including the suspension of HVAC equipment, pipe work, fire protection/sprinkler systems, suspended ceilings and electrical equipment from structural or secondary beams.
DECkING FIxINGSLindapter produce a range of high quality, cost effective building services connections designed to fit inside the dovetail shaped re-entrant channel of decking profiles, compatible with all major manufacturers including CMF, Corus, Kingspan, SMD and Richard Lees.
FLOOR FIxINGSLindapter’s concept extends to their innovative fixings that connect steel flooring to supporting steelwork without the need of on-site drilling or welding. Access to the underside of the flooring is not required, eliminating the need for costly scaffolding or elevated floors. Installation can be carried out quickly and safely from above, often by one person, significantly reducing costs.
RAIL FIxINGSFast and convenient fixings are available for over head equipment, track work cable troughs, electrification bracketry, station monitors and the holding down of low speed rail lines. Lindapter also design and manufacture bespoke products for individual customer requirements.
Protective Coatings
ELECTRO ZINC PLATING Cr6 Free : BS 7371-3:1993, BS 3382 Part 2 and ISO 4042 This is a bright zinc finish and generally would be a maximum of 8/10 microns of zinc coating, this should be used only for short term protection or in non aggressive enviroments such as Europe.
HOT DIP GALVANISINGBS 7371-6:1998, DIN 267 Part 10 and ISO 1461 This is a deep grey finish and would always be a minimum of 45 microns, this coating has a very thick layer of zinc and would be recommended for highly aggressive environments such as those in the Middle East.
SHERARDISINGBS 4921 Class 1 This is a matt grey finish (almost black) and would always be a minimum of 30 microns, this is a zinc dust diffusion process at high temperatures (320-500 degrees C). This coating again is recommended for highly aggressive environments such as those in the Middle East, and also has a very high salt spray resistance suitable for coastal use.
HYDROGEN EMBRITTLEMENT During any zinc application by electroplating the supplier must ensure that hydrogen embrittlememt does not occur during the process, this is the diffusion of hydrogen ions into the metal which causes high stresses in the structure of the steel and can give rise to delayed or spontaneous brittle fracture. Embrittlement is caused by pre-treatments like pickling prior to electroplating, this is avoided by either very stringent cleaning procedures or by reheating the product after the zinc process for a period of time and at a set temperature based on ISO 4042:1989. OTHER AVAILABLE COATINGS: MECHANICAL GALVANISINGGREENKOTE®DACROMET 320 or 500SHERAPLEXDELTA COAT DELTA SEALGEOMETJS 500XYLAN 1070
Most fasteners used in the structural fabrication market are supplied with some form of corrosion resistant coating, this is to give the product more durability in the connection enhancing lasting strength, visual appearance and ease of installation and dismantling.
Corrosion is caused directly by the particular environment it is exposed to, during both storage and service, so dependant on the levels of corrosive elements within the atmosphere BAPP Group would suggest that one of the following three coatings be applied to the assembly.
