Apple doesn’t want to let you inside your iPhone, even if all you want to
do is fix it.
That’s what repair company iFixit claims, at least. The company recently
discovered that Apple has quietly switched the screws in the latest
shipments of the iPhone 4 from a basic Phillips head to a tamper-resistant
screw that you can’t remove with any screwdriver you’d buy at a hardware
store.
The screw in question is called a “Pentalobe” (see r... 阅读全帖 |

不符合实际施工请多多原谅:-)
1.machine bolt & carriage bolt
2.wood screw & large screw
3.nail
machine bolt & carriage bolt都是带washer,是靠wash和bolt thread互相的摩擦或本
身钉杆的强度受力,用来连接可以两边reach的部件(要不没法拧罗帽了:-) 要先在部见上
打空
screw没有washer,靠screw thread和部件的磨擦受力,钉时要先打孔,孔比screw本身要
小一点,好能保证拧进去很紧,一般drywal都是这个
nail没有thread,摩擦要比screw小很多,常见用来钉木地板,家居之类,不用打孔直接
钉
bolt/screw/nail钉的结实不结实和其本身强度有关,更和被钉的部件受力强度有关,dry
wall就是本身太酥经不住劲,bolt &screw有时在连接wood时会加垫片也是这个道理,钢水
泥砖头没事儿...
另外screw & nail都要保 |

s*********0 发帖数: 2045 | 3 I have 9 Gladiator tracks in my garage. Word of advice: forget their own
screws. They are crap and will most definitely strip. How many screws get 1
star online reviews? They really screwed it up.
Instead use these torx head self-drilling screws:

Ohio State Is Screwed (But You Wouldn’t Know It Based On Media Coverage)
You’re not hearing anything about Ohio State at all from most sports media
which is why I took a break from two top-secret longer form writing projects
to let you know what you need to know about Ohio State and Jim Tressel.
The immediate takeaway is simple — and salty — Ohio State and Jim Tressel
are fucked. (I used screwed in the headline so y’all wouldn’t get busted
