The British Standards Institution (BSI) administers British Standards as the UK's National Standards body. British Standards L (BS-L) relate to different grades of aluminium alloys and light alloy materials such as magnesium and apply to different product forms (shapes) such as sheets/plates, bars and tubes.

Sourced from different manufacturers they are offered as their OEM parts or as parts of our own labelled (AVIATIONEU NEW ERA) product lines. They can be supplied in different Metric pre-cut ot cut-to-order (CTO) dimensions and heat treatments (tempers) and they are sold in pieces or bulk (tons). A brief overview of offered BS-L metal products commonly used in Aerospace with reference to the commercial (trade) name of the respective aluminum alloy, and their correlation to their US Standards' counterparts is included below (see table). Depending on application requirements,  certain US Standard metals can be used as alternatives to their BS-L counterparts.

2014/2014A(*)

Applicable forms: plates, sheets and strips, bars, tubes as per respective BS-L Standards.

The 2014 aluminum alloy is high-strength aerospace alluminum alloy alloyed with copper (3.90-5.00%). Often includes cladding with 1050A aluminium and heat treated to T3  or T4 conditions, as in the case of sheets, to meet respective BS L163, and BS L164 Standard specifications.  Clad sheets are typically used in aerospace and defense components, structural and high technology applications. Use of copper enables them to retain their high strength after their heat treatment while cladding, as part of the mill production process, enhances their corrosion resistance capabilities. 

2024/2024A(*)

Applicable forms: sheets.

The 2024 aluminum alloy (with copper as the primary alloying element) is also known as aerospace grade aluminum. It is commonly used in aircraft structural applications due to its high strength and fatigue resistance and those requiring high stress & strain resistance in aviation and industrial applications. This alloy is stronger but less versatile than 6061, which is more corrosion resistant, easier to weld, and more suited to machining, but less strong than the 7075.  2024A 1050A Alclad sheets relate to BS-L Standards BS L109 and BS L110.

7075

Applicable forms: plates, sheets and strips, bars.

7075 aluminium alloy is an aluminium alloy with zinc as the primary alloying element.  It is one of the most commonly used aluminium alloys for highly stressed structural applications such as aircraft structural parts. Respective BS-L Standards for different forms of 7075 aluminum include BS 2 L95 for T651 plates, BS 2 L88 for T6 clad sheets and strips, BS L160, BS L161, and BS L70 for bars.

For additional information, please refer to the supplied documentation or contact us for a quotation.

(*) The letter "A" in the alloy classification system indicates a modified version of the respective standard alloy with generally no distinction in material properties or performance betwwen the two.

HI-SHEAR Fasteners are patented fasteners of HI-SHEAR CORPORATION (Patent Holder), subsidiary of LISI AEROSPACE, a manufacturer of advanced aerospace fasteners and installation equipment used in space, military and commercial vehicles. Depending on the fastener, they are made by quality fastener manufacturers (licensees) in different  countries including but not limited to LISI AEROSPACE companies, HOWMET ALCOA / SIMMONDS / FAIRCHILD, PCC  SPS, and others. 

The HI-SHEAR rivet pin range offers a versatile solution for most of structural assemblies. They consist a very common type of threaded fastener used for clearance, transition and low interference fit throughout the airframe (metallic and composite), from wings to fuselage, in engine fairings, and more. Easily installed from one side, by one person with conventional tooling.

HI-SHEAR rivet pin product portfolio includes the original HI-LOK™ (HL™) system, the latest HI-LITE™ (HST™) pins with an improved recess and HI-TIGUE™ (HLT™) pins with improved fatigue benefits. They can be used in shear and/or tension applications on plain or sloped surfaces and feature controlled preload, a wide range of sizes and variety of materials and coatings for installation in all structures.

Most fasteners are mainly loaded in shear. That should be the only way for rivets as their tension capability is relatively low. Whenever there is a substantial tension load in a fastener, a threaded bolt should be used.

Additional information is available in Product Description section and the supplied documentation.

AISI/SAE(*) 4130 and 4140 grade steels are low-alloy steels containing chromium and molybdenum as common composition elements. Both are are popular steel materials due to their properties. AISI 4130 grade steel shows good overall combinations of strength, toughness and fatigue strength with good atmospheric corrosion resistance while AISI 4140 grade steel features a high fatigue strength, abrasion and impact resistance, toughness, and torsional strength. Both alloys are weldable with the use of all conventional techniques (AISI 4130 alloy's lower carbon composition compared to AISI 4140 allows easier welding) and machinable in the annealed condition. To make them stronger they need to be subjected to heat treatment, such as annealing, cold working, etc. 4140 and 4130 grade steels are wideky used in aerospace, oil and gas, automotive, agricultural and defense industries.

Anchor nuts (aka nutplates or anchor plates) are terms used interchangeably and relate to stamped sheet metal fasteners with an internally threaded tube and a plate with two clearance holes for rivets. Initially designed and still extensively used in aerospace applications, they are today also used in automotive, motorsports, and other industries in blind mounted panel applications where hex nuts cannot be used or an attached nut is required for ease of maintenance. They can be Fixed or Floating, the latter being easier to install due to their built-in nut (threaded hole) able to "float" slightly thus providing a convenient connection point for threaded rods, such as bolts, from the backside. In the case of Fixed anchor nuts, the built-in nut is static (i.e. without the capability to “float”) and the threaded bolt must be positioned perfectly over the hole. Self-locking anchor nuts are those with a built-in locking mechanism preventing them from loosening over time from vibrations.

Anchor nuts are offered in Imperial (in.) and Metric thread sizes, in different materials (e.g. Carbon Steel, Steel alloys, CRES), finishes such as Cadmium or Cadmium Free Zinc Nickel platings (compliant to EU Regulations) with or without dry film lubrication. They come in various styles/configurations (e.g. with one or two lugs, full size or miniatures, countersunk, corner, right-angled bodies, etc.). They conform to different U.S., European and international standards such as the US Military MS and NASM, German DIN LN, French AFNOR NF, British BS, ISO and others.

Depending on the selected nutplate, aerospace anchor nuts are produced by different manufacurers, such as HOWMET AEROSPACE (formerly ARCONIC) or PAOLO ASTORI, and others, and offered as respective OEM parts or as parts of our own labelled (AVIATIONEU NEW ERA) product lines in the case of those used in industrial applications. Sold in pieces or packs of specified number of anchor nuts per pack indicated after the letters "PK" in the product SKU.
