The shear capacity given in the tables must be reduced for large packings, large grip lengths, kidney shaped slots or long joints when applicable. Faying surface preparation is required for these joints. Engineering Book Store // -->, Engineering ISO Metric Hardware Design Data, GD&T Training Geometric Dimensioning Tolerancing. The tension capacity of the bolt is given by: The shear capacity of the bolt is given by. .style8 {font-size: 12px} Cookies are only used in the browser to improve user experience. Applications Some Applications Include: 1) The maximum loads in the table above are based on allowable tensile stress of 12 kpsi - reduced by 25% to 9 kpsi allowable stress. Values in bold are less than the single shear capacity of the bolt. The torque values can only be achieved if nut (or tapped hole) has a proof load greater than or equal to the bolt's minimum ultimate tensile strength. Bolt Loading Capacities. Stripper bolt material: 4137 33~38 HRC, strength class 10.9.) From the table at right, for a strength class of 10.9 and a maximum allowable load of 200 kgf, the suitable bolt is a 318[kgf]M8. { These applications will - due to browser restrictions - send data between your browser and our server. Ultimate Tensile and Proof loads for metric bolts according ISO 898-1 "Mechanical properties of fasteners made of carbon steel and alloy steel - Part 1: Bolts, screws and studs with specified property classes — Coarse thread and fine pitch thread". d) For structural bolting: 70000 N (M12), 95500 N (M14) and 130000 N (M16).

Home The following table of thread sizes for coarse and fine pitch thread was created using the standard sizes from ASME B1.13M. Engineering ToolBox - Resources, Tools and Basic Information for Engineering and Design of Technical Applications! Grade 8.8 Bolts per. Unbraced spans can reduce beam load carrying capacity. Similarly a grade 9.8 bolt will begin to stretch at 80% of its breaking load. }, , Engineering ISO Metric Hardware Design Data Non-preloaded Ordinary Bolts. Head Markings Metric Bolt Class Mechanical Properties Proof Load (MPa) Min Yield (MPa) Min Tensile Strength (MPa) Class 8.8 Medium carbon steel, quenched and tempered 580-600 640-660 800-830 Class 10.9 Alloy Steel, quenched and tempered 830 940 1040 Class 12.9 Alloy Steel, quenched and tempered 970 1100 1220 A2 Stainle If long slotted or kidney shaped holes are used, bearing values should be multiplied by 0.5. kN. 11.1 Bolt capacities The types of bolts covered are: Grades 4.6, 8.8 and 10.9, as specified in BS 4190 [17]: ISO metric black hexagon bolts, screws and nuts. For example, a grade 12.9 bolt will begin to stretch when the load on the bolt is 90% of the breaking load. Eye Bolt - Bs4278 With Metric Sizing 136 Eye Bolt ... the thread sizes listed in the table below may be wrongly matched with the risk that the Eye Bolt may pull out of the threaded hole below the design load. There are currently no comments available. Engineering News Values in italic are greater than the double shear capacity of the bolt. Refer to Page 62 of the Unistrut Engineering Catalog for reduction factors for unbraced lengths. The nominal bolt load curve is shown as a thick solid blue line. Clamp loads estimated as 75% of proof load for specified bolts. DFM DFA Training t Thickness of the connected material, in. kgf loads in the same way. Minimum Proof Loads With so many bolts available these days it is essential to understand the strengths and weaknesses different bolts have when compared to one another. ; Non-preloaded and preloaded HSFG bolts as specified in BS 4395 [18]: High strength friction grip bolts and associated nuts and washers for structural engineering. Bearing values assume standard clearance holes. Design properties for metric hex bolts (Typical coarse pitch thread) Dimensions Hole … ; If oversize or short slotted holes are used, bearing values should be multiplied by 0.7. Ultimate Tensile and Proof loads for metric bolts according ISO 898-1 "Mechanical properties of fasteners made of carbon steel and alloy steel - Part 1: Bolts, screws and studs with specified property classes — Coarse thread and fine pitch thread". 1. Beam loads are given in total uniform load (W Lbs) not uniform load (w lbs/ft or w lbs/in). Bolt capacity is based on the smaller of bolt shear and material bearing capacities, and, if desired, is adjusted based on bolt spacing (i.e., reductions in capacity are possible when bolt spacing is less than optimal). document.write('') AddThis use cookies for handling links to social media. End distance equal to 2 x bolt diameter, Thickness in mm of material passed through, The tensile stress area (At ) is obtained from standards.

Table 6.3 shows that snug-tightened bolts of Property Class 8.8 (i.e. Grade 8.8 Bolts per. Some of our calculators and applications let you save application data to your local computer. Acceptable clamp load is typically 75% of proof load. Lubed means cleaned, dry bolts, lubricated with standard medium viscosity machine oil. Working load limits for eye bolts are based on a straight vertical lift in a gradually increasing manner. View Full Specs.
