Each hexagonal standoff is 3/16" wide and has threading running through the entire length, similar to an elongated hex nut. A variety of lengths are available with either 2-56 or 4-40 threading: Alternatives available with variations in these parameter(s): [length thread type Select variant… ](https://core-electronics.com.au/catalog/select-by-specification?parameters=0J76%2C0J109&product=2087&products=2080) Longer standoffs can be made by stacking multiple F-F standoffs on a single screw. [M-F (male-female) standoffs](https://core-electronics.com.au/hardware/spacers-standoffs.html) are also available, and can be screwed together or combined with F-F versions to make longer standoffs: | BodyLength | Thread | Price per4-pack | | BodyLength | Thread | Price per4-pack | |---|---|---|---|---|---|---| | 0.25" | [\#2-56](https://core-electronics.com.au/aluminum-standoff-1-4-length-2-56-thread-m-f-4-pack.html) | [\#4-40](https://core-electronics.com.au/aluminum-standoff-1-4-length-4-40-thread-m-f-4-pack.html) | $1.75 | | 11 mm | [M2.5, 4mm](https://core-electronics.com.au/aluminum-standoff-for-raspberry-pi-11mm-length-4mm-m2-5-thread-m-f-4-pack.html) | $1.95 | | 0.375" | [\#2-56](https://core-electronics.com.au/aluminum-standoff-3-8-length-2-56-thread-m-f-4-pack.html) | [\#4-40](https://core-electronics.com.au/aluminum-standoff-3-8-length-4-40-thread-m-f-4-pack.html) | $1.75 | | 11 mm | [M2.5, 6mm](https://core-electronics.com.au/aluminum-standoff-for-raspberry-pi-11mm-length-6mm-m2-5-thread-m-f-4-pack.html) | $1.95 | | 0.5" | [\#2-56](https://core-electronics.com.au/aluminum-standoff-1-2-length-2-56-thread-m-f-4-pack.html) | [\#4-40](https://core-electronics.com.au/aluminum-standoff-1-2-length-4-40-thread-m-f-4-pack.html) | $1.75 | | 18.6 mm | [M2.5, 6mm](https://core-electronics.com.au/aluminum-standoff-for-raspberry-pi-18-6mm-length-6mm-m2-5-thread-m-f-4-pack.html) | $2.25 | | 0.75" | [\#2-56](https://core-electronics.com.au/aluminum-standoff-3-4-length-2-56-thread-m-f-4-pack.html) | [\#4-40](https://core-electronics.com.au/aluminum-standoff-3-4-length-4-40-thread-m-f-4-pack.html) | $1.95 | | | | | | 1.0" | [\#2-56](https://core-electronics.com.au/aluminum-standoff-1-length-2-56-thread-m-f-4-pack.html) | [\#4-40](https://core-electronics.com.au/aluminum-standoff-1-length-4-40-thread-m-f-4-pack.html) | $2.25 | | | | | | 1.25" | [\#2-56](https://core-electronics.com.au/aluminum-standoff-1-1-4-length-2-56-thread-m-f-4-pack.html) | [\#4-40](https://core-electronics.com.au/aluminum-standoff-1-1-4-length-4-40-thread-m-f-4-pack.html) | $2.95 | | | | | | 1.5" | [\#2-56](https://core-electronics.com.au/aluminum-standoff-1-1-2-length-2-56-thread-m-f-4-pack.html) | – | $3.15 | | | | | Pololu carry a variety of 2-56 and 4-40 [screws and hex nuts](https://core-electronics.com.au/hardware/screws-nuts.html) that can be used with these standoffs. **People often buy this product together with:** | [![Aluminum Standoff: 1/4" Length, 4-40 Thread, M-F (4-Pack)](https://a.pololu-files.com/picture/0J2790.100.jpg?d3091ae4258eaa3405c0b163fcc26c8b)](https://core-electronics.com.au/aluminum-standoff-1-4-length-4-40-thread-m-f-4-pack.html) | [Aluminum Standoff: 1/4" Length, 4-40 Thread, M-F (4-Pack)](https://core-electronics.com.au/aluminum-standoff-1-4-length-4-40-thread-m-f-4-pack.html) | |---|---| | [![Aluminum Standoff: 1/8" Length, 4-40 Thread, F-F (4-Pack)](https://a.pololu-files.com/picture/0J3728.100.jpg?247249378f36a854952714d618b964fa)](https://core-electronics.com.au/aluminum-standoff-1-8-length-4-40-thread-f-f-4-pack.html) | [Aluminum Standoff: 1/8" Length, 4-40 Thread, F-F (4-Pack)](https://core-electronics.com.au/aluminum-standoff-1-8-length-4-40-thread-f-f-4-pack.html) | |---|---| | [![Aluminum Standoff: 3/8" Length, 4-40 Thread, F-F (4-Pack)](https://a.pololu-files.com/picture/0J3732.100.jpg?7f93f1bba979ea617bfa7221b1f6fc73)](https://core-electronics.com.au/aluminum-standoff-3-8-length-4-40-thread-f-f-4-pack.html) | [Aluminum Standoff: 3/8" Length, 4-40 Thread, F-F (4-Pack)](https://core-electronics.com.au/aluminum-standoff-3-8-length-4-40-thread-f-f-4-pack.html) | |---|---| **Dimensions** | Length: | 0.188 in | |---|---| **General specifications** | Gender: | Female-Female | |---|---| | Thread type: | 4-40 | ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/a/l/aluminum_standoff_3_16_inch_length_4_40_thread_f_f__4_pack___pololu_2087__00.jpg)
