Product Overview

*Lug Nuts / Bolts*
H&R offers a large selection of specialty wheel tightening bolts and lug nuts, available with a multitude of thread sizes and seat types. Lug nuts and bolts may be used as replacement parts or with other H&R products. And, it’s always a good idea to have a couple extras on hand.

*WHEN ORDERING WHEEL BOLTS, PLEASE FOLLOW THESE GUIDELINES*
*a)* If possible, name the brand of wheel.

*b)* New bolts must be longer than the original bolts by the width of the wheel spacer used.

*c)* The bolt head must be identical to the existing bolt:
• Taper 60deg - End digit 01
• Round head for M12/d24 mm, for M14/d28 mm - End digit 02
• Round head for M12/d26 mm (e.g. OE VAG-wheels) - End digit 03
• Flat head for Porsche original wheels M14 x 1.5 - End digit 06

*d)* Safety guidelines
(Minimum number of turns for wheel bolts / nuts):
• M12 x 1.25 = 8.0 turns = approx. 10 mm of load bearing shaft length
• M12 x 1.50 = 6.5 turns = approx. 10 mm of load bearing shaft length
• M12 x 1.75 = 6.5 turns = approx. 12 mm of load bearing shaft length
• M14 x 1.25 = 9.0 turns = approx. 12mm of load bearing shaft length
• M14 x 1.50 = 7.5 turns = approx. 12 mm of load bearing shaft length
• 1/2" UNF = 8.0 turns = approx. 11 mm of load bearing shaft length

Please ensure that the wheel bolts do not damage any part of the brake system (ABS sensors, etc.). Turn the wheel by hand and check clearance on the inside of the hub. The wheel should rotate freely. (Maximum tolerance for some vehicles is only 2mm -- i.e. Rear Axle Mercedes).

• Extended lengths for use with wheel spacers or as OE replacements
• High quality wheel fastening bolts, studs and nuts
• made in Germany
• Some applications available in silver or black
• Wide variety of lengths, thread pitch, and seat designs

Note in regards to wheels and tyres.

Unless otherwise stated, wheels and tyres are supplied individually. They are not typically listed as a full set since most vehicles run different widths and offsets front to rear. Please carefully check your PCD, width and offset (ET) when choosing wheels or wheel and tyre packages. If you need more information or clarification, contact StreetFX customer support prior to ordering.

Please carefully review the description and specifications for details on inclusions or any variations. Some items may be sold individually or in sets, and images may occasionally depict additional products or quantities not included in your purchase.
