Aluminum 7075 fasteners are most commonly used for their combination of high strength and low weight. Alloyed primarily with zinc, they exhibit strength that is comparable to many grades of steel at a fraction of the density. Aluminum 7075 can be tempered to several different conditions (including 7075-T6) which offers different levels of strength. Commonly used for high-stress aircraft parts, Aluminum 7075 bolts offer good fatigue resistance and toughness.

Compared to aluminum alloy 2024, 7075 bolts are typically used in applications where high strength and low weight are critical, whereas 2024 is more suited for cyclic fatigue. When weighing their attributes against 6061 which is structural aluminum, 6061 offers better corrosion resistance and machinability, but does not have the same high strength as aluminum 7075 fasteners.

Key Attributes
o  High strength compared to other aluminum alloys
o  Lightness: Aluminum weighs about one third of steel
o  Good fatigue strength
o  Good ductility and toughness
o  Economic strength-to-weigh ratio
o  Low density
o  Non-magnetic
o  Usable to ~752F / 400C

Aluminum 7075 Strength Chart

Aluminum 7075 Screws  

12 Point Screws	12 point screws are most often used for applications that need a higher torque bolt than a socket head cap screw. We offer 12 points in 1/4" diameter or larger. The only drawback is Aluminum 7075 12 point screws are less economical and require a high minimum quantity due to the complexity of production.	o  IFI-115 o  MIL SPEC o  DIN 34822 o  DIN 34821
Button Head Cap Screws	For a wide-clamping area and low-profile fastener, Aluminum 7075 button head cap screws are an ideal choice. Button head screws are also used when you must fasten a material that is too thin to counter bore.	o ASME B18.3 o ASME 18.3.4M o DIN 7380 / ISO 7380
Flat Head Screws	Flat head screws have a standard 82° countersink angle and typically feature a slotted or socket driver. Aluminum 7075 flat heads are also available with angles ranging from 60° -120° upon request. Phillips, torx and tamperproof drivers are also available depending on size, quantity and material.	o  ASME B18.3 o  ASME B18.3.6 o  DIN 963 / ISO 2009 o  DIN 965 / ISO 7046 o  DIN 7991 / ISO 10642
Hex Head Cap Screws	Aluminum 7075 hex head cap screws are the most common fastener. They have an added washer face providing tighter dimensional tolerances over a hex bolt which lacks this element. Aluminum 7075 hex head cap screws provide high clamping force and easy access.	o ASME B18.6.3 o DIN 931 / ISO 4014 o DIN 933 / ISO 4017 o DIN 961 / ISO 8676
Pan Head Screws	Aluminum 7075 pan head screws have a rounded head and are ideally used for small diameter and low torque applications. They typically feature a slotted driver.	o ASME B18.6.3 o DIN 7985 o DIN 921 o DIN 85 / ISO 1580 o DIN 84 / ISO 1207   (cheese head) o DIN 966 / ISO 7047   (raised counter sunk)
Security Screws	When applications demand unwanted removal or tampering, Aluminum 7075 security screws provide protection because they cannot be unfastened using an common driver. Tamper-proof screws are produced in a wide variety of head styles, as well as custom per print.
Set Screws	Aluminum 7075 set screws have no head. This  fastener has a slotted or socket driver on one end and a unique point on the other. Set screws are available with cup, cone, flat, dog and half-dog points.	o ASME B18.3 o DIN 913 / ISO 4026 o DIN 914 / ISO 4027 o DIN 915 / ISO 4028 o DIN 916 / ISO 4029
Socket Head Cap Screws	Aluminum 7075 socket head cap screws are ideal for low clearance applications that require a safe and secure fastener.	o ASME B18.3 o DIN 912 / ISO 4762 o DIN 7984
Vented Screws	Aluminum 7075 vented screws provide a way to out-gas application contaminents through a vertical hole drilled from the screw head through the threaded shaft. Vented screws are ideal for vacuums / high vacuums. Nimonic vented screws are available a variety of head styles.

Aluminum 7075 Bolts 

Hex Head Bolts	Similar to hex head cap screws but without the washer face, Aluminum 7075 hex bolts are a good choice when high clamping force is needed for easily accessible applications.	o ASME B18.2.1 o DIN 931 / ISO 4014 o DIN 933 / ISO 4017
Shoulder Bolts	Aluminum shoulder bolts have a head, smooth shoulder section (for rotating parts) and botttom threaded portion. Shoulder bolts typically have a socket driver.	o ASME o DIN 7379 / ISO 7379 o ISO 7370

Aluminum 7075 Nuts 

Hex Nuts	We offer Aluminum 7075 nuts in several styles including: finished hex nuts, jam nuts and heavy hex nuts.	o ASME B18.16.3 o ASME B18.2.2 o DIN 439 / ISO 4035 o DIN 934 / ISO 4032 o DIN 986
Lock Nuts	Aluminum 7075 lock nuts are offered as all-metal and polymer/nylon insert styles. All-metal lock nuts such as stover and flexloc are ideal for high temperatures and even load distribution. Nylon (polymer) insert lock nuts are more economic but can only be used when temperatures are under 350°F.	o ASME B18.16.3M o DIN 980 / ISO 7042 /     ISO 19513 o DIN 6923 / ISO 4161 o DIN 985 / ISO 10511 /   ISO 7040
