hex key size for Loprinzi neck adjustments

[Telecaster2017!]

I want to buy the right hex key set. The adjustment but is very deep near the neck block.

If it's a 1970's vintage guitar the company that built it is long since out of business. (Mr. LoPrinzi himself is still building classical guitars in a one man shop.) I'd suggest that you take the guitar with you to a hardware store and try all the hex keys and/or Allen wrenches until you find the correct one. You might need to get a long one.

PS: If you manage to track down Mr. LoPrinzi I'm sure he can tell you the correct size.

Maybe just buy one quality set of standard and metric allen wrenches. Essential tools to have anyway IMHO. For that application I would not want to get the ones with ball ends.

I have a 1980 LoPrinzi "Augustino" if you can't find the size within the next few days I can see what fits mine..let me know if I can help. I tweaked it a few years back, I want to say 4mm but I'm not positive. Maybe figure out the length you need first, I have long ones I usually use.

The original company (with both brothers) split up in the 70s but Augie and his daughter I believe are still going in Clearwater FL. He actually got famous in the ukulele realm.

From acoustic music.org:
"In 1972 brothers Augustino and Thomas LoPrinzi founded the LoPrinzi Guitar Company in New Jersey. They started to sell stock in the company and soon had a successful business going with 17 employees. In 1973 his instruments caught the attention of Maark Corporation (a subsidiary of AMF); the firm began buying up a controlling interest in the LoPrinzi Guitar Company as a way to move into the guitar business. Three years later, LoPrinzi Guitars, Inc. was producing 80 guitars a month for customers in five countries.

The 1970’s were an important period for guitar production. The 1960’s surge in interest in acoustic instruments had stretched the ability of the major manufactures to meet the public demand. The general quality level of the major manufacturer’s instruments was at an all time low. Gibsons and Martins from that period are among the least sought-after instruments by players and collectors alike. The void was filled by small shop producers like LoPrinzi Guitars, Inc. These shops produced instruments that lived up to the standards of the finest periods. They found a market and a strong following of devoted players.

Augustino LoPrinzi, after growing tired of overseeing production and fearful of the direction the company was taking under AMF management, sold his interest to Maark Corporation. He felt the demands of mass production would jeopardize the quality of his instruments.

Augie’s philosophy of work and success is a traditional one: If you’re only out to make money, you’ll never get anywhere. You have to maintain a perspective regarding money. “Do good work and the money will come,” was the theory instilled in Augustino by his father.

Refusing to sign a “non-compete” clause with Maark, he opened “Augustino Guitars” two weeks later—and literally moved next door to his original plant. He continued to produce guitars in that location until 1978, and then moved to Clearwater Florida. The AMF-owned LoPrinzi company continued producing guitars with Thomas LoPrinzi, and finally closed their doors in 1980. Years later, Augustino contacted AMF/Maark Corporation to request his old trademark back. Working with vice president Dick Hargraves, Augie finally regained legal control of his name.

Currently Augustino LoPrinzi Guitars includes a full line of steel string guitars, classical guitars and ukuleles. Augie continues to build instruments full time with his daughter, Donna LoPrinzi.

Mine required a socket size 10mm if I remember correctly.
